Hello,

I'm wondering what are good tools for UI testing that can be used for Java?
I've heard of Selenium but I'm wondering if there are any other/better ones?

Thanks so much!

Thanks so much! I'll look into using AsyncTask

Seems the run method is only being executed once when the app starts and then doesn't run again.

Thank you, I have changed it ppgResult and registerThread

Hi,

I have a Thread that runs from the MainActivity and I'm wondering how I can update the UI from the result in the Thread?

The MainActivity looks like:
public class TestJNIActivity extends Activity implements OnClickListener {    TextView myTextField;    protected static int PPGresult;    public static SensorInterface Register_Thread = new SensorInterface();    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        if (!Python.isStarted()) {            Python.start(new AndroidPlatform(this));        }        myTextField = (TextView)findViewById(R.id.myTextField);        if((Register_Thread.getState() == Thread.State.NEW)){            SensorInterface.runThread = true;            Register_Thread.start();        }        Log.w(TAG, "STOPPED THREAD 22222" + Register_Thread.getState());    }

And in the SensorInterface Thread:
public class SensorInterface extends Thread{    private int PPGresult;    private class Result{        public int result;    } ...      Python py = Python.getInstance();      PyObject pyObject = py.getModule("filterPython").callAttr("RunCode");      String returnString = pyObject.toString();      String test = returnString.replace("\\", "").replace("\"", "");      test = test.replace("result", "\"result\"").replace("[", "").replace("]", "");      Gson gson = new Gson();      Result resFromJson = gson.fromJson(test, Result.class);      TestJNIActivity.PPGresult = resFromJson.result;

I would like to update the TextView with PPGresult

I tried adding to TestJNIActivity:
runOnUiThread(new Runnable() {                @Override                public void run() {                    if (PPGresult == 0) {                        myTextField.setText("0");                    }                    else if (PPGresult == 1) {                        myTextField.setText("1");;                    }                }            });

but nothing seems to happen.

Any ideas would be appreciated, thank you!

I have an android app which turns on a sensor on my device and collects and displays data in the app to the user.

On the home screen the user presses "START" which opens a new page that displays the data.
When the user presses the back button it take them back to the home page.

The problem I am facing is when the user presses "START" again, the display page still shows values from the previous test.

Here is the AndroidManifest:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.test"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="19"        android:targetSdkVersion="19" />    <uses-permission android:name="android.permission.READ_PHONE_STATE" />    <uses-permission android:name="android.permission.INTERNET"/>    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>    <!--<uses-permission android:name="com.google.android.things.permission.USE_PERIPHERAL_IO" />    <uses-permission android:name="com.google.android.things.permission.MANAGE_INPUT_DRIVERS" />-->    <application        android:allowBackup="true"        android:icon="@drawable/company"        android:label="Company"        android:theme="@style/TempTheme" >        <activity            android:clearTaskOnLaunch="true"            android:name="MainActivity"            android:label="Company" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>    </application> </manifest>

Part of the MainActivity code:
private void showFragment(boolean show, String tag) { PlaceholderFragment fragment = (PlaceholderFragment) getFragmentManager().findFragmentByTag(tag); final FragmentTransaction loadTransaction = getFragmentManager().beginTransaction(); View fragmentContainer = findViewById(R.id.fragmentContainer); if (show) { mCurrentTag = tag; } else { mCurrentTag = null;; } if (!show && FRAGMENT_TAG_RESULTS.equals(tag)) { if (!(TextUtils.isEmpty(mHR) || TextUtils.isEmpty(mBP) || TextUtils.isEmpty(mMaxHP) || TextUtils.isEmpty(mMinHP))) { final SharedPreferences sh = getSharedPreferences(TEST_LOG_PREF, MODE_PRIVATE); sh.edit().putString(formatDate(new Date(), "yyyy-MM-dd-HH:mm:ss"), mTemp).apply(); mTemp = ""; } } if (fragment == null && show) { fragment = new PlaceholderFragment(tag); loadTransaction.replace(R.id.fragmentContainer, fragment, tag); getFragmentManager().executePendingTransactions(); } if (show) { fragmentContainer.setVisibility(View.VISIBLE); loadTransaction.show(fragment); } else { loadTransaction.hide(fragment); fragmentContainer.setVisibility(View.GONE); } loadTransaction.commitAllowingStateLoss(); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.hrbp_main); findViewById(R.id.btn_test_temp).setOnClickListener(this); mTemp = (TextView) findViewById(R.id.txt_temp); ClearHistory(); } @Override protected void onNewIntent(Intent intent) { Log.i("DHYCO", "onNewIntent:"+intent); super.onNewIntent(intent); } @Override public void onBackPressed() { // TODO Auto-generated method stub if (mCurrentTag != null) { showFragment(false, mCurrentTag); enableSensorOrNot(false); startFlashSensor(false); ClearHistory(); serviceconnection.StopCount(); mFlashThread = null; } else super.onBackPressed(); } private void ClearHistory() { Tempresult = -1; Tempcircle = (ImageView) findViewById(R.id.Tempcircle); } @Override protected void onStop() { // TODO Auto-generated method stub super.onStop(); ClearHistory(); enableSensorOrNot(false); startFlashSensor(false); serviceconnection.StopCount(); mFlashThread = null; }

Thanks so much!

Thank you! We seemed to have solved the problem adding mFlashThread = null; in to the onBackPressed() if statement.

Thanks again for your help!

Thanks so much!

I think I only have this one thread running:
private void startFlashSensor(boolean start) { if (start && mFlashThread == null) { mStartFlash = true; mFlashThread = new Thread(new Runnable() { @Override public void run() { while (mStartFlash && !Thread.interrupted()) {                                           ....                                           ServiceConnection serviceconnection = new ServiceConnection(date, mTemp);       serviceconnection.GetData();

Hi, thanks so much for your reply.

The code for when the back button is pressed looks like:
@Override public void onBackPressed() { // TODO Auto-generated method stub if (mCurrentTag != null) { showFragment(false, mCurrentTag); enableSensorOrNot(false); startFlashSensor(false); serviceconnection.StopCount(); } else super.onBackPressed(); } @Override protected void onStop() { // TODO Auto-generated method stub super.onStop(); enableSensorOrNot(false); startFlashSensor(false); serviceconnection.StopCount(); }

The thread, both for sensor thread and network is started (or stop) by startFlashSensor()

when it is false, the method stops

but the network continues, even the part inside the statFlashSensor method.

So I guess my question now is, how to stop both threads (network and sensor)?

I have an android app which turns on a sensor on my device and collects data, the data is then sent via http requests and a response is returned back to the app.
However when the back button is pressed it doesn't go back to the home page of the app, instead it crashed with:

unfortunately app has stopped

And I get these errors:
W/System.err:     at java.lang.Thread.run(Thread.java:841) I/System.out: result: No answer    New result: No answer W/dalvikvm: threadid=13: thread exiting with uncaught exception (group=0x41644c08) E/AndroidRuntime: FATAL EXCEPTION: Thread-166    Process: com.example.testApp, PID: 13140    com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $        at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory$Adapter.read(ReflectiveTypeAdapterFactory.java:226)        at com.google.gson.Gson.fromJson(Gson.java:932)        at com.google.gson.Gson.fromJson(Gson.java:897)        at com.google.gson.Gson.fromJson(Gson.java:846)        at com.google.gson.Gson.fromJson(Gson.java:817)        at com.example.testApp.ServiceConnection.main(ServiceConnection.java:183)        at com.example.testApp.ServiceConnection.GetData(ServiceConnection.java:74)        at com.example.testApp.HRBPActivity$1.run(HRBPActivity.java:250)        at java.lang.Thread.run(Thread.java:841)     Caused by: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $        at com.google.gson.stream.JsonReader.beginObject(JsonReader.java:386)        at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory$Adapter.read(ReflectiveTypeAdapterFactory.java:215)        at com.google.gson.Gson.fromJson(Gson.java:932)         at com.google.gson.Gson.fromJson(Gson.java:897)         at com.google.gson.Gson.fromJson(Gson.java:846)         at com.google.gson.Gson.fromJson(Gson.java:817)         at com.example.testApp.ServiceConnection.main(ServiceConnection.java:183)         at com.example.testApp.ServiceConnection.GetData(ServiceConnection.java:74)         at com.example.testApp.HRBPActivity$1.run(HRBPActivity.java:250)         at java.lang.Thread.run(Thread.java:841) 

If I press the back button before data gets collected then the app goes back properly to the home screen.

It seems that the ServiceConnection class is still running which is causing the error.

Any suggestions would be great,
Thanks so much!

Hello,

I have a few round circles in my app. I would like to change their colour depending on the response I get from an http request.
The cirlces look like:
<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"    android:shape="oval"    >    <size        android:width="80dp"        android:height="80dp" />    <solid        android:color="#00FF00"/> </shape>
and are being added in as FrameLayout like:
   <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal"        >        <TextView            android:layout_width="50dp"            android:layout_height="wrap_content"            android:layout_weight="1"            android:text="@string/temperature"            android:textSize="20sp" />        <FrameLayout            android:layout_width="32dp"            android:layout_height="match_parent"            android:background="@drawable/circle"></FrameLayout>    </LinearLayout>

Then in the java code the http request is being made:
try {            response = client.newCall(request).execute();            System.out.println(response.body().string());        } catch (IOException e) {            e.printStackTrace();        }        return String.valueOf(response);    }

So if the response is 1, the circle will turn green, if the response is 2 the circle will turn blue etc.

Thanks so much!

Hello,

I am wondering if there is a way to make a few circles that change colour depending on a trigger?
For ex. if the app is displaying temperature of the user, the circle will be green if the temperature is in a normal range, red if the temperature is a low grade fever and blue if a high grade fever. (And another circle for other measurements etc)

Can this be done in android studio itself or will I have to add something like JavaFx or the like?

Thanks so much!

Hi Ron McLeod,

Just wanted to thank you again for your help! We used the OkHttp library as you suggested and it worked!

(We used verison com.squareup.okhttp3:okhttp:3.12.0 for Api 19)

Good to know API 19 is still being used and actually has some benefits too:)

Thanks so much again for all the help!

Thanks so much!

Wow that is very interesting re apache.

At the moment the API needs to stay at 19 to be compatible with the devices the app is running on.

Perhaps though as you mentioned, I can use another library. I think java.net.HttpURLConnection; is compatible with API 19, so maybe that could be a solution.

Thanks again for all your help!

Thanks so much! Really appreciate your time helping me!

It seems one of the SDKs we are using in the app is calling maven.apache could that be the problem? and is there anything we can do about it?(since we need this sdk)
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Thank you!

I tried adding the dependency but sill got the error:(

I checked the external library and I can see the class is there.
