Debugger disconnecting in Android Studio when debugging a home screen widget

Question

I am trying to debug an Android home screen widget application that I made. When pressing a button on the widget, the debugger starts and then it just disconnects from the VM. No reason is given. I am using Windows 10.

This is what the logs say:

D/Atlas: Validating map... D/libEGL: loaded /system/lib/egl/libEGL_emulation.so D/libEGL: loaded /system/lib/egl/libGLESv1_CM_emulation.so D/libEGL: loaded /system/lib/egl/libGLESv2_emulation.so  D/         ] HostConnection::get() New Host Connection established 0xef0394f0, tid 3709  I/OpenGLRenderer: Initialized EGL, version 1.4 D/OpenGLRenderer: Enabling debug mode 0 W/EGL_emulation: eglSurfaceAttrib not implemented  W/OpenGLRenderer: Failed to set EGL_SWAP_BEHAVIOR on surface 0xef1485e0, error=EGL_SUCCESS D/roboguice.RoboGuice: Using annotation database(s).

I also pulled traces.txt, but haven't found any obvious error message. Maybe I don't know what to look for. When first placing the widget on the screen the debugger doesn't disconnect. This happens with both the official Emulator and GenyMotion. The emulator is Google Nexus 5 5.1.0 API 22.

These are the Gradle build setting:

android {     compileSdkVersion 25     buildToolsVersion "25.0.0"     defaultConfig {         applicationId "com.gdbd.geedeebeedee"         minSdkVersion 15         targetSdkVersion 25         versionCode 1         versionName "1.0"         testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dependencies {     compile fileTree(dir: 'libs', include: ['*.jar'])     androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {         exclude group: 'com.android.support', module: 'support-annotations'     })      compile group: 'com.google.code.gson', name: 'gson', version: '2.3.1'     compile 'com.android.support:appcompat-v7:25.0.0'      compile 'org.roboguice:roboguice:3.+'     provided 'org.roboguice:roboblender:3.+'      testCompile 'junit:junit:4.12' } 

Does anyone know what is happening and why I cannot debug? Thanks.

Edit 1:

Apparently the process dies.

Edit 4 GdbdWidgetBase

@Inject     GdbdWidgetRecords gdbdWidgetRecords;      public void onHandleUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {         // Perform this loop procedure for each App Widget that belongs to this provider         for (int widgetIndex = 0; widgetIndex < appWidgetIds.length; widgetIndex++) {             int widgetId = appWidgetIds[widgetIndex];             Log.d(TAG, "Updating widget index: " + widgetIndex + " with id: " + widgetId);              GdbdWidgetRecord todaysRecord = gdbdWidgetRecords.getTodaysRecord();              RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.gdbd_widget);              if(todaysRecord.getCurrentStatus() == DayStatus.GOODDAY)                 views.setImageViewResource(R.id.btnClicker, R.drawable.ic_gd);             else if(todaysRecord.getCurrentStatus() == DayStatus.BADDAY)                 views.setImageViewResource(R.id.btnClicker, R.drawable.ic_bd);             else if(todaysRecord.getCurrentStatus() == DayStatus.NOTSET)                 views.setImageViewResource(R.id.btnClicker, R.drawable.ic_undecided);               Intent intent = new Intent(context, GdbdWidgetBase.class);             intent.setAction(CHANGE_DAY_STATUS);             intent.putExtra(WIDGET_ID_EXTRA, widgetId);             PendingIntent changeStatusIntent = PendingIntent.getBroadcast(context, widgetId, intent,                     PendingIntent.FLAG_CANCEL_CURRENT);             views.setOnClickPendingIntent(R.id.btnClicker, changeStatusIntent);              scheduleUpdateAtMidnight(context, widgetId);              appWidgetManager.updateAppWidget(widgetId, views);         }     }      @Override     public void onHandleReceived(Context context, Intent intent) {         Log.d(TAG, "Received intent: " + intent.getAction());         //Log.d(TAG,"getDebugUnregister: " + (getDebugUnregister()?"true":"false"));          if (CHANGE_DAY_STATUS.equals(intent.getAction())) {              int appWidgetId = intent.getIntExtra(WIDGET_ID_EXTRA, -1);             if (appWidgetId >= 0) {                 GdbdWidgetRecord todaysRecord = gdbdWidgetRecords.getTodaysRecord();                 Log.d(TAG, "today record: " + todaysRecord.toString());                 DayStatus newDayStatus = DayStatus.NOTSET;                  if(todaysRecord.getCurrentStatus() == DayStatus.NOTSET)                     newDayStatus = DayStatus.GOODDAY;                 else if(todaysRecord.getCurrentStatus() == DayStatus.GOODDAY)                     newDayStatus = DayStatus.BADDAY;                 else if(todaysRecord.getCurrentStatus() == DayStatus.GOODDAY)                     newDayStatus = DayStatus.NOTSET;                  Log.d(TAG, "newDayStatus: " + newDayStatus);                  gdbdWidgetRecords.changeTodaysStatus(newDayStatus);                 onHandleUpdate(context, AppWidgetManager.getInstance(context), new int[]{appWidgetId});             }         }     }      private void scheduleUpdateAtMidnight(Context context, int widgetId) {         Calendar calendar = Calendar.getInstance();         calendar.setTimeInMillis(System.currentTimeMillis());         calendar.set(Calendar.SECOND, 1);         calendar.set(Calendar.MINUTE, 0);         calendar.set(Calendar.HOUR_OF_DAY, 0);         calendar.add(Calendar.DAY_OF_YEAR, 1);          Intent updateAtMidnightIntent = new Intent(context, GdbdWidgetBase.class);         updateAtMidnightIntent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);         updateAtMidnightIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, new int[]{widgetId});          PendingIntent broadcastIntent = PendingIntent.getBroadcast(context, widgetId + 1,                 updateAtMidnightIntent, PendingIntent.FLAG_CANCEL_CURRENT);          AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);          if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {             alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), broadcastIntent);         } else {             alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), broadcastIntent);         }     } 

Edit 5 The breakpoint is always in the onReceive() method of my AppWidget. For other intents like android.appwidget.action.APPWIDGET_ENABLED it takes more before the debugger stops, but my app still dies

Whereas for my own intent that is sent when a button is pressed within the widget it takes 10 seconds.

Answer 1

I went to the emulated device's Settings -> Developer Options and enabled "Show all ANRs" and now a warning appears "Your application is not responding" and I can tap "WAIT" and it seems to work.

Answer 2

This is not a solution to stop the detaching. But you can re-attach the debugger directly afterwards. You can attach the debugger to running processes with the button in the toolbar:

I know that it is not ideal, but maybe it is already enough to continue debugging for you.
