Intent intent = new Intent(); String packageName = context.getPackageName(); PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); if (pm.isIgnoringBatteryOptimizations(packageName)) intent.setAction(Settings.ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS); else { intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS); intent.setData(Uri.parse(“package:” + packageName)); } context.startActivity(intent); Kotlin val intent = Intent() val pm : PowerManager = getSystemService(Context.POWER_SERVICE) as PowerManager if (pm.isIgnoringBatteryOptimizations(context.packageName)) { intent.action = Settings.ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS } else { intent.action = Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS intent.data = Uri.parse(“package:${context.packageName}”) } context.startActivity(intent) … Read more

Send request over WiFi (without connection) even if Mobile data is ON (with connection) on Android M

Wakelock and doze mode

Based on some testing, using a Nexus 5 with the the final(?) preview of Android 6.0 installed: Holding a PARTIAL_WAKE_LOCK is insufficient to block Doze mode — the device will still doze, even though you have the WakeLock and are trying to do regular work (e.g., setExactAndAllowWhileIdle() to get control every minute) Keeping the screen … Read more

Android Marshmallow: Test permissions with Espresso?

With the new release of the Android Testing Support Library 1.0, there’s a GrantPermissionRule that you can use in your tests to grant a permission before starting any tests. @Rule public GrantPermissionRule permissionRule = GrantPermissionRule.grant(android.Manifest.permission.ACCESS_FINE_LOCATION); Kotlin solution @get:Rule var permissionRule = GrantPermissionRule.grant(android.Manifest.permission.ACCESS_FINE_LOCATION) @get:Rule must be used in order to avoid java.lang.Exception: The @Rule ‘permissionRule’ must … Read more
