The following code throws a runtime exception when trying to start a camera with deprecated Camera API for android:
E/MediaRecorder: start failed: -19

I really tried using the new camera2 API, but had no luck with it... The service I am trying to create should open the camera in a service and record video in the background until the camera should be closed.

The code which the MainActivity uses in order to open the camera:
package com.example.songtry2;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import android.Manifest;
import android.app.IntentService;
import android.app.Service;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
0);
} else {
Toast.makeText(this, "wow storage", Toast.LENGTH_SHORT).show();
Log.d("camera","camera");
}
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.RECORD_AUDIO},
0);
} else {
Toast.makeText(this, "Camera on! Cool!!!", Toast.LENGTH_SHORT).show();
Log.d("camera","camera");
}
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA},
0);
}
RecordIntentService.startActionRecord(this);
}
}
'getCameraInstance' function used in order to search for a front-facing camera and open it for use:
public static Camera getCameraInstance(){
int cameraCount = 0;
Camera cam = null;
Camera.CameraInfo cameraInfo = new Camera.CameraInfo();
cameraCount = Camera.getNumberOfCameras();
for (int camIdx = 0; camIdx < cameraCount; camIdx++) {
Camera.getCameraInfo(camIdx, cameraInfo);
if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
try {
cam = Camera.open(camIdx);
} catch (RuntimeException e) {
Log.e(TAG, "Camera failed to open: " + e.getLocalizedMessage());
}
}
}
return cam;
}
The function which uses the camera in the Recording Service code:
private boolean prepareVideoRecorder(){
mCamera = getCameraInstance();
recorder = new MediaRecorder();
recorder.reset();
//recorder.setCamera(Camera.Face);
// Step 1: Unlock and set camera to MediaRecorder
mCamera.unlock();
recorder.setCamera(mCamera);
// Step 2: Set sources
recorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
// Step 3: Set a CamcorderProfile (requires API Level 8 or higher)
//recorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
CamcorderProfile profile = CamcorderProfile.get(Camera.CameraInfo.CAMERA_FACING_FRONT,CamcorderProfile.QUALITY_LOW);
recorder.setProfile(profile);
// Step 4: Set output file
recorder.setOutputFile(getOutputMediaFile(MEDIA_TYPE_VIDEO).toString());
// Step 6: Prepare configured MediaRecorder
try {
recorder.prepare();
recorder.start();
} catch (IllegalStateException e) {
Log.d(TAG, "IllegalStateException preparing MediaRecorder: " + e.getMessage());
System.out.println("ERROR" + e.getMessage());
releaseMediaRecorder();
return false;
} catch (IOException e) {
Log.d(TAG, "IOException preparing MediaRecorder: " + e.getMessage());
releaseMediaRecorder();
return false;
}
return true;
}
private void releaseCamera(){
if (mCamera != null){
mCamera.release(); // release the camera for other applications
mCamera = null;
}
}
