i need to write a java code to execute some command for automation purpose.
what i want to achieve is pushing image to camera.

i tried to write a code to input text via adb and it works.. it looks like this

public void inputTextByCode(String deviceId, String input) throws IOException{  

        welcomeTheTester();

        String commandStr = "input keyboard text ";



        Process process = null;

        String commandString = "";

        if(deviceId != null) {

            commandString = String.format("%s", "adb -s " + deviceId + " shell " + commandStr + input);

        } else {

            commandString = String.format("%s", "adb shell " + commandStr + input);

        }



        System.out.print("Command is "+commandString+"n");

        try {

            process = ProcessHelper.runTimeExec(commandString);

        } catch (IOException e) {

        }

        BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));

        String line;

        while ((line = reader.readLine()) != null) {

            System.out.print(line+"n");

        }

    }

it will produce adb command as

adb -s 192.168.28.101:5555 shell input keyboard text testing

could i do the same,, but with camera? how could i push image / some kind of stream to android camera?

You have to create a dummy camera app. Most app which require image capture from camera implement this logic.

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

if (takePictureIntent.resolveActivity(getPackageManager()) != null) {

   startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);

}

and implement this code to get the image from camera.

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {

        Bundle extras = data.getExtras();

        Bitmap imageBitmap = (Bitmap) extras.get("data");

        mImageView.setImageBitmap(imageBitmap);

    }

}

So, you have to create a dummy camera app which should have an Activity like this

<activity

 android:name="com.android.camera.CaptureActivity"

 android:label="@string/app_name"

 android:theme="@style/Theme.Camera"

 android:configChanges="orientation|screenSize|keyboardHidden"

 android:windowSoftInputMode="stateAlwaysHidden|adjustPan">

 <intent-filter>

 <action android:name="android.media.action.IMAGE_CAPTURE" />

 <category android:name="android.intent.category.DEFAULT" />

 </intent-filter>

</activity>

and you should return something like this.

Bitmap bitmap = CameraUtil.makeBitmap(data, 50 * 1024);

bitmap = CameraUtil.rotate(bitmap, orientation);

Log.v(TAG, "inlined bitmap into capture intent result");

mActivity.setResultEx(Activity.RESULT_OK,

Intent("inline-data").putExtra("data", bitmap));

mActivity.finish();

In this way your QR code scanner app will think it has opened a legit camera app, but your dummy app will be opened, and your app will return the image which you want
