Intent innerIntent = new Intent(Intent.ACTION_GET_CONTENT); //”android.intent.action.GET_CONTENT”

Intent wrapperIntent = Intent.createChooser(innerIntent, null);

((Activity) context).startActivityForResult(wrapperIntent, requestCode);

 

//視訊

Intent innerIntent = new Intent(Intent.ACTION_GET_CONTENT);

innerIntent.setType(contentType); //String VIDEO_UNSPECIFIED = “video/*”;

Intent wrapperIntent = Intent.createChooser(innerIntent, null);

((Activity) context).startActivityForResult(wrapperIntent, requestCode);

 

//新增音訊

Intent innerIntent = new Intent(Intent.ACTION_GET_CONTENT);

innerIntent.setType(contentType); //String VIDEO_UNSPECIFIED = “video/*”;

Intent wrapperIntent = Intent.createChooser(innerIntent, null);

((Activity) context).startActivityForResult(wrapperIntent, requestCode);

 

//錄音

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);

intent.setType(ContentType.AUDIO_AMR); //String AUDIO_AMR = “audio/amr”;

intent.setClassName(“com.android.soundrecorder”,

“com.android.soundrecorder.SoundRecorder”);

((Activity) context).startActivityForResult(intent, requestCode);

 

//拍攝視訊

int durationLimit = getVideoCaptureDurationLimit(); //SystemProperties.getInt(“ro.media.enc.lprof.duration”, 60);

Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);

intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);

intent.putExtra(MediaStore.EXTRA_SIZE_LIMIT, sizeLimit);

intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, durationLimit);

startActivityForResult(intent, REQUEST_CODE_TAKE_VIDEO);

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); //”android.media.action.IMAGE_CAPTURE”;
