SOLVED, SEE COMMENT --- I never get a callback from Camera.takePicture(), I see that in logcat. What is missing? How do I make takePicture()... take a picture?! Most of this is directly from Android developers camera guide. I want to take pictures programmatically without any preview or user action. Using the built in camera app works fine. SDK 16.
And in the manifest I do have added:
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera"
android:required="true" />
The code:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button bTake = (Button)findViewById(R.id.b_take);
boolean boo = safeCameraOpen(camId);
Camera.Parameters parameters = mCamera.getParameters();
mCamera.setParameters(parameters);
bTake.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
mCamera.takePicture(shutter, null, null, picture);
Log.e(getString(R.string.app_name), "After takePicture");
}
});
}// END onCreate
/* Camera operations */
private ShutterCallback shutter = new ShutterCallback() {
@Override
public void onShutter() {
Log.e(getString(R.string.app_name), "onShutter");
}
};
private PictureCallback picture = new PictureCallback() {
@Override
public void onPictureTaken(byte[] arg0, Camera arg1) {
Log.e(getString(R.string.app_name), "onPicTaken");
}
};
/* Starting up and closing down*/
private boolean safeCameraOpen(int id) {
boolean qOpened = false;
try {
releaseCamera();
mCamera = Camera.open(id);
qOpened = (mCamera != null);
} catch (Exception e) {
Log.e(getString(R.string.app_name), "failed to open Camera");
e.printStackTrace();
}
return qOpened;
}
private void releaseCamera() {
if (mCamera != null) {
((Camera) mCamera).release();
mCamera = null;
Log.e(getString(R.string.app_name), "cam released");
}
}}
