<!-- AndroidManifest.xml -->
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2. CameraActivity

"CameraActivity" is used to take pictures.

Start CameraActivity

private void intentCameraActivity() {
       Intent intent = new Intent(this, CameraActivity.class);
       intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
       startActivityForResult(intent, REQUEST_CODE_CAMERA);
   }

Intent Extra Option

• intent.putExtra(CameraActivity.EXTRA_JPEG_QUALITY, int jpegQuality);
• intent.putExtra(CameraActivity.EXTRA_CAPTURE_MIN_WIDTH, int minWidth);
• intent.putExtra(CameraActivity.EXTRA_CAPTURE_MAX_WIDTH, int maxWidth);
• intent.putExtra(CameraActivity.EXTRA_CAPTURE_MIN_HEIGHT, int minHeight);
• intent.putExtra(CameraActivity.EXTRA_CAPTURE_MAX_HEIGHT, int maxHeight);
• intent.putExtra(CameraActivity.EXTRA_LIMIT_CAPTURE_COUNT, int maxCount);

Result Capture Uris

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
            case REQUEST_CODE_CAMERA:
                if (resultCode != RESULT_OK) {
                    return;
                }
                ArrayList<Uri> captureUris = data.getParcelableArrayListExtra(CameraActivity.REQUEST_EXTRA_CAPTURE_URIS);
                if (captureUris == null) {
                    return;
                }
                for (Uri uri : captureUris) {
                    Log.e("TAG", "uri: " + uri);
                }
                Toast.makeText(this, "captureCount = " + captureUris.size(), Toast.LENGTH_SHORT).show();
                break;
        }
    }

3. CameraPreviewActivity

"CameraPreviewActivity" is used to check or delete pictures taken by CameraActivity.

Start CameraPreviewActivity

private void intentCapturePreviewActivity() {
        if (mCaptureUris.size() > 0) {
            Intent intent = new Intent(this, CameraPreviewActivity.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
            intent.putParcelableArrayListExtra(CameraPreviewActivity.EXTRA_CAPTURE_URIS, mCaptureUris);
            startActivityForResult(intent, REQUEST_CODE_CAMERA_PREVIEW_ACTIVITY);
        }
    }

Result Capture Uris

@Override
   protected void onActivityResult(int requestCode, int resultCode, Intent data) {
       super.onActivityResult(requestCode, resultCode, data);
       switch (requestCode) {
           case REQUEST_CODE_CAMERA_PREVIEW_ACTIVITY:
               if (resultCode != RESULT_OK) {
                   return;
               }
               
               ArrayList<Uri> newCaptureUris =
                       data.getParcelableArrayListExtra(CameraPreviewActivity.REQUEST_EXTRA_CAPTURE_URIS);

               if (mCaptureUris.size() != newCaptureUris.size()) {
                   mCaptureUris.clear();
                   mCaptureUris.addAll(newCaptureUris);
               }
               break;
       }
   }
