android-orientation

I have managed to get Video capture to work for a custom camera experience (i.e. using MediaRecorder, Camera, SurfaceView, etc.). But if I am recording a video and change the orientation of the device, video capture stops. Is there way to continue the capture after the orientation change? If fact I want the capture to continue no matter how many times the orientation changes. I imagine it might all have to do with savedInstanceState and saving the file that I pass to mRecorder.setOutputFile(my file) . If that's correct, what else am I missing? Or is there a more standard way to handle

I have a fragment with EditText and add it into the layout using transactions. But if I rotate to landscape the soft keyboard disappears. public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); if (getSupportFragmentManager().findFragmentById(R.id.fragmentContainer) == null) { getSupportFragmentManager().beginTransaction() .add(R.id.fragmentContainer, new FragmentWithEditText()) .commit(); } } } I want keyboard state still unchanged after rotate using

How to retain the form data in the webview after the change the orientation ? I have used onSaveInstanceState() and I have restored the previous state using restoreState(savedInstanceState) .

Note: I would not be using android:configChanges="keyboardHidden|orientation" as I need keyboard input for my application after orientation

I have an Android application using LinearLayout as main layout with a SurfaceView filled by camera preview. In this I inflate another LinearLayout with three Buttons and a custom TextView. I would like the camera preview to stay always in Landscape orientation and the overlay layout changing according to the device orientation. I tried setting android:screenOrientation="landscape" in the manifest for the activity but then (of course) also the inflated layout stays always fixed, while not setting the android:screenOrientation property also the camera preview rotate, slowing down the app and

I'm trying to get yaw of an android device expressed in euler angles. To be clear i dont want 'Azimuth' (which is the angle to magnetic north) I want the rotation of the 'z' axis of an android device as shown in this picture. This (IMHO) should be the axis used in some car games to determine the amount of steering. It is my understanding I could just use the Accelerometer values (without the magnetic fields) but I'm unable to get the determined value. (probably due to a lack of understanding of how rotation matrixes works). Can someone point me toward the right direction? Hoan Nguyen If you

Portrait mode (It's normal) Press screen lock, Activity: onPause() ; Unlock the screen, Activity: onResume() . Landscape mode (It's strange) Press screen lock, Activity: onPause() -> onStop() -> onDestroy() -> onCreate() -> onStart() -> onResume() which loads the Portrait layout; Unlock the screen, Activity: onPause() -> onStop() -> onDestroy() -> onCreate() -> onStart() -> onResume() and loads the Landscape layout.
