Camera Intent shows issues in Marshmallow and Nougat

Question

My Sample app is working well with the earlier version(before Android M) but getting crash while performing compression after being fetched from internal storage since height and width is coming -1.

Bitmap bmp = BitmapFactory.decodeFile(filePath, options);    
int actualHeight = options.outHeight;
int actualWidth = options.outWidth;

After doing some research, I come to the conclusion that the the file is getting corrupted at the time of clicking an image in Android N & M, may be since I'm saving the images as a temporary file not sure.

The following code I'm using for clicking an image:

public void takePhoto() {
    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    File f = null;
    try {
        f = setUpPhotoFile();
        mCurrentPhotoPath = f.getAbsolutePath();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, FileProvider.getUriForFile(ctx.getContext(),"com.example.fileprovider", f);
        }
        else{
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
        }

    } catch (IOException e) {
        e.printStackTrace();
        f = null;
        mCurrentPhotoPath = null;
    }

    ctx.startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}

fileprovider.xml

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="images" path="Pictures/AIADMK/"/>
</paths>

manifest.xml

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.example.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/fileprovider" />
</provider>

The below is the crash error:

Where am I going wrong?

Answer 1

Add required permissions check before requesting to camera and in addition

For Android N, add this code in onCreate() method of your Application class.

   if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.N) {
        StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
        StrictMode.setVmPolicy(builder.build());
    }

No need to specify provider or path with this.

Note-Using provider is still the best way to do same task.

hope it help someone !

Answer 2

The issue is the latest version of Android because in Android M & N we have to use FileProvider in order to persist the file and for earlier version we can use Uri.fromFile(f). I do have to change my fileprovider.xml as listed below:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">
    <external-path name="myexternalimages" path="Pictures/AIADMK" />
</paths>

1. Check for permission for API 23 and above refer this http://www.coderzheaven.com/2016/07/29/simple-example-on-using-camera-access-permission-in-android-marshmallow/

2. Check your onActivityResult() is it give you output in bitmap or uri.

3.If you are getting output in uri convert it into bitmap.

Answer 4

check permission for marshmallow

if (Build.VERSION.SDK_INT >= 23 &&
                    (ContextCompat.checkSelfPermission(yourActivityContext, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)) {
                ActivityCompat.requestPermissions(yourActivityContext, new String[]{Manifest.permission.CAMERA}, 2//requestCode);
            } else {
                selectImage();
            }

And override onRequestPermissionsResult of Activity

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
      case 2: //same request code you provided in code above

                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                   selectImage();

                }


            break;
       }
}
