Android Exclude Some Camera Intent - android

I'm developing an app that will need to use a camera using the file input from WebView.
So this is the code that I write and it is working with the google camera.
In my webchromeclient
webView.setWebChromeClient(new WebChromeClient()
{
//The undocumented magic method override
//Eclipse will swear at you if you try to put #Override here
// For Android 3.0+
#SuppressWarnings("unused")
public void openFileChooser(ValueCallback<Uri> uploadMsg) {
mUploadMessage = uploadMsg;

// Create the storage directory if it does not exist
if (! imageStorageDir.exists()){
imageStorageDir.mkdirs();

}
}
// Set up the intent to get an existing image

chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);
startActivityForResult(chooserIntent, MainActivity.FILECHOOSER_RESULTCODE);
return true;
}
});
Then this is my activityresult:
private Uri imageUri;
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
if (Build.VERSION.SDK_INT >= 21){
if(requestCode != FILECHOOSER_RESULTCODE || mFilePathCallback == null) {
super.onActivityResult(requestCode, resultCode, intent);
return;
}
Uri[] results = null;
// Check that the response is a good one
if(resultCode == Activity.RESULT_OK) {
if(intent == null) {
// If there is not data, then we may have taken a photo
if(mCameraPhotoPath != null) {
results = new Uri[]{Uri.parse(mCameraPhotoPath)};
}
} else {
String dataString = intent.getDataString();
if (dataString != null) {
results = new Uri[]{Uri.parse(dataString)};
}
}
}
mFilePathCallback.onReceiveValue(results);
mFilePathCallback = null;
return;
}else{
if(requestCode==FILECHOOSER_RESULTCODE)
{
if (null == this.mUploadMessage) {
return;
}
Uri result;
if (resultCode != RESULT_OK) {
result = null;
} else {
result = intent == null ? this.imageUri : intent.getData(); // retrieve from the private variable if the intent is null
}
this.mUploadMessage.onReceiveValue(result);
this.mUploadMessage = null;
}
}
}
It is working with image upload or taking photo using the google camera.
My Question is how to exclude some camera intent when making the input action?
For example I want to remove camera 360 or retrica in the list, how to do it?

Edit this part:
for(ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent i = new Intent(captureIntent);
i.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
i.setPackage(packageName);
i.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
cameraIntents.add(i);
}
To This one:
for(ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent i = new Intent(captureIntent);
if(packageName.equals("ihate.this.package")||packageName.equals("begone.unwanted.package")){
Log.i("camera", res.activityInfo.packageName+" blocked!");
}else{
i.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
captureIntent.setPackage(packageName);
i.setPackage(packageName);
i.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
cameraIntents.add(i);
}
}
If you want to know the package name just Log the res.activityInfo.packageName
You can do the same approach for android 5.0

You can restrict available apps by setPackage.

No, what you are trying to do is not supported. You can either use setPackage to restrict it to one particular app, or leave the package null, and allow any capable app to handle the intent.

What is required to get onActivityResult to fire from a camera selection?

I have the following code which creates an intent to either choose a photo from a gallery of the camera:
public void onPhotoButtonClick(View view) {
File root = new File(Environment.getExternalStorageDirectory() + File.separator + "photos" + File.separator);
root.mkdirs();
String fileName = String.format("photo_%s.jpg", System.currentTimeMillis());
File sdImageMainDirectory = new File(root, fileName);
photoUri = Uri.fromFile(sdImageMainDirectory);
List<Intent> cameraIntents = new ArrayList<Intent>();
Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
PackageManager packageManager = getPackageManager();
List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for(ResolveInfo resolvedInfo : listCam) {
String packageName = resolvedInfo.activityInfo.packageName;
Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(packageName, resolvedInfo.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
cameraIntents.add(intent);
}
Intent galleryIntent = new Intent();
galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_PICK);
Intent chooserIntent = Intent.createChooser(galleryIntent, "Select source");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));
startActivityForResult(chooserIntent, SELECT_PHOTO);
}
The issue is when I take a photo with the camera it is not activating the onActivityResult which is below:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d(TAG, String.valueOf(requestCode));
Log.d(TAG, String.valueOf(resultCode));
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PHOTO) {
final boolean isCamera;
if (data == null) {
isCamera = true;
} else {
final String action = data.getAction();
isCamera = MediaStore.ACTION_IMAGE_CAPTURE.equals(data.getAction());
}
Uri selectedImageUri;
if (isCamera) {
selectedImageUri = photoUri;
} else {
selectedImageUri = data == null ? null : data.getData();
}
photoText.setText(selectedImageUri.toString());
Log.d(TAG, selectedImageUri.toString());
}
}
}
I have the below in my manifest:
<uses-feature android:name="android.hardware.camera" android:required="false"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Am I missing something?

Android - Why can't I start the choosePictureIntent?

Im trying to start the choosePictureIntent. This is done by clicking on an image in an Ap
#Override
public void imageClicked(int position) {
if(data.get(position).getImgUri() != null) {
// IGNORE THIS
Intent intent= new Intent(context, FullScreenActivity.class);
intent.putExtra("data", data.get(position));
context.startActivity(intent);
} else {
// THIS IS THE CODE
Object[] chooseData;
chooseData = Utils.getChoosePictureIntent(context, context.getPackageManager());
Intent chooserIntent = (Intent) chooseData[0];
chooserIntent.putExtra("data", data.get(position)); // data is an array of information
chooserIntent.putExtra("outputFileUri", (Uri) chooseData[1]);
((Activity) context).startActivityForResult(chooserIntent, PICTURE_REQUEST);
}
}
When I click on the image, nothing happens, but I know that the else statement gets executed. After that, if I click on the view besides the image, the whole app freezes.
There are no error messages.
Any help is appreciated.
The source of getChoosePictureIntent():
public static String getUniqueFileName(String prefix, String surfix) {
return prefix + System.currentTimeMillis() + surfix;
}
public static Object[] getChoosePictureIntent(Context context, PackageManager manager) {
final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "imagedir" + File.separator);
root.mkdirs();
final String fName = Utils.getUniqueFileName("img_purchase_", ".jpg");
final File sdImageMainDirectory = new File(root, fName);
Uri outputFileUri = Uri.fromFile(sdImageMainDirectory);
// Camera.
final List<Intent> cameraIntents = new ArrayList<Intent>();
final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final PackageManager packageManager = manager;
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for(ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
cameraIntents.add(intent);
}
// Filesystem.
final Intent galleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
// Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent, context.getString(R.string.picture_chooser));
// Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));
return new Object[]{chooserIntent, outputFileUri};
}
If you are using targetSdk >=24, then you need to add File Provider in order to replace the File Uri received from Camera App to Content Uri because API level 24 has blocked File Uri from another app for security reason.You can check out this link for more info

Image file is empty on return from activity on Android

Using code from this answer: https://stackoverflow.com/a/12347567/734687
I use the following code to let a user submit a picture to my Android application.
private void openImageIntent() {
File outputFile = null;
try {
outputFile = File.createTempFile("tmp", "face", getCacheDir());
} catch (IOException pE) {
pE.printStackTrace();
}
mOutputFileUri = Uri.fromFile(outputFile);
// Camera.
final List<Intent> cameraIntents = new ArrayList<Intent>();
final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final PackageManager packageManager = getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for(ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mOutputFileUri);
cameraIntents.add(intent);
}
// Filesystem.
final Intent galleryIntent = new Intent();
galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_PICK);
// Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");
// Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));
startActivityForResult(chooserIntent, 42); //XXX 42?
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == 42) {
final boolean isCamera;
if (data == null) {
isCamera = true;
} else {
final String action = data.getAction();
if (action == null) {

} else {
isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
}
}
Uri selectedImageUri = null;
if (isCamera) {
selectedImageUri = mOutputFileUri;
} else {
selectedImageUri = data == null ? null : data.getData();
}
loadFacePicture(selectedImageUri);
}
}
}
However the Uri selectedImageUri leads to an empty file on loadFacePicture(selectedImageUri);
What did I missed ?
This is what I endup doing.
This seemed to be the source of the issue:
intent.putExtra(MediaStore.EXTRA_OUTPUT, mOutputFileUri);

final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
cameraIntents.add(intent);
}
// Filesystem.
final Intent galleryIntent = new Intent();
galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_PICK);
// Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");
// Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));
startActivityForResult(chooserIntent, 42);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 42) {
Bitmap bmp = null;
if (data.hasExtra("data")) {

Camera Intent auto crop like card IO? or Show a surface(dotted Line) and auto crop After Capture

I am using Camera Intent to capture and Upload..For Default camera
So here I followed this to crop image just like card IO..
But the above one is separate camera its not Intent
I want surface holder should be placed inside the camera intent .. is it possible if so can any one suggest me..
I want this surface crop before capture.... only for camera intent.. not for gallery... just like Card IO.... But for crop only...not OCR..
So I want to use the above functionality in this

Is it Possible can any one suggest me.. regarding this...
Here I have tried with Auto crop by placing intent for crop... but It show preview like surface from where to where its cropping.... for Default Camera through Intent..... Not for Custom Camera activity...

Can you please help?
Thank you
I'm calling this method in another class by making object of this call
Never instantiate an Activity with new. It won't get properly initialized, and calling any activity or context method won't work. So it's no good for anything you'd want to use it for.
Instead, pass in a Context as a parameter to methods that need it like this.
To instantiate an activity, use startActivity() with Intent.
