Jak wybrać obraz i wideo dla interfejsu API> 19

Oto przetestowany kod obrazu i wideo, który będzie działał dla wszystkich interfejsów API mniejszych niż 19 i większych niż 19.

Wizerunek:

if (Build.VERSION.SDK_INT <= 19) {
                        Intent i = new Intent();
                        i.setType("image/*");
                        i.setAction(Intent.ACTION_GET_CONTENT);
                        i.addCategory(Intent.CATEGORY_OPENABLE);
                        startActivityForResult(i, 10);
                    } else if (Build.VERSION.SDK_INT > 19) {
                        Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                        startActivityForResult(intent, 10);
                    }

if (Build.VERSION.SDK_INT <= 19) {
                        Intent i = new Intent();
                        i.setType("video/*");
                        i.setAction(Intent.ACTION_GET_CONTENT);
                        i.addCategory(Intent.CATEGORY_OPENABLE);
                        startActivityForResult(i, 20);
                    } else if (Build.VERSION.SDK_INT > 19) {
                        Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
                        startActivityForResult(intent, 20);
                    }    

.

     @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == Activity.RESULT_OK) {
           
            if (requestCode == 10) {
                Uri selectedImageUri = data.getData();
                String selectedImagePath = getRealPathFromURI(selectedImageUri);
            } else if (requestCode == 20) {
                Uri selectedVideoUri = data.getData();
                String selectedVideoPath = getRealPathFromURI(selectedVideoUri);
            }

     public String getRealPathFromURI(Uri uri) {
            if (uri == null) {
                return null;
            }
            String[] projection = {MediaStore.Images.Media.DATA};
            Cursor cursor = getActivity().getContentResolver().query(uri, projection, null, null, null);
            if (cursor != null) {
                int column_index = cursor
                        .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                cursor.moveToFirst();
                return cursor.getString(column_index);
            }
            return uri.getPath();
        }

Odtwarzaj dźwięki za pomocą SoundPool

public class PlaySound extends Activity implements OnTouchListener {
    private SoundPool soundPool;
    private int soundID;
    boolean loaded = false;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            View view = findViewById(R.id.textView1);
            view.setOnTouchListener(this);
            // Set the hardware buttons to control the music
            this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
            // Load the sound
            soundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
            soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
                    @Override
                    public void onLoadComplete(SoundPool soundPool, int sampleId,
                                    int status) {
                            loaded = true;
                    }
            });
            soundID = soundPool.load(this, R.raw.sound1, 1);

    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    // Getting the user sound settings
                    AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
                    float actualVolume = (float) audioManager
                                    .getStreamVolume(AudioManager.STREAM_MUSIC);
                    float maxVolume = (float) audioManager
                                    .getStreamMaxVolume(AudioManager.STREAM_MUSIC);
                    float volume = actualVolume / maxVolume;
                    // Is the sound loaded already?
                    if (loaded) {
                            soundPool.play(soundID, volume, volume, 1, 0, 1f);
                            Log.e("Test", "Played sound");
                    }
            }
            return false;
    }
}
