Question

i want to take a Photo after clicking on a button. But i am getting NullPointerException when trying to get URI with FileProvider.

Here is my ErrorCode:

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.res.XmlResourceParser android.content.pm.PackageItemInfo.loadXmlMetaData(android.content.pm.PackageManager, java.lang.String)' on a null object reference

The Problem-Line seems to be:

mUri = FileProvider.getUriForFile(getApplication().getApplicationContext(),
            "ibas.provider", file);

Here´s my Code:

public void takePicture(View view) throws IOException {

    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    try{
        File file =  createImageFile();

        mUri = FileProvider.getUriForFile(getApplication().getApplicationContext(),
                "ibas.provider", file);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, mUri);
        startActivityForResult(intent, REQUEST_IMAGE_CAPTURE);
    } catch (IOException e){
        e.printStackTrace();
    }

}


private File createImageFile() throws IOException {

    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = "file:" + image.getAbsolutePath();
    return image;
}

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

    String path = "sdcard/orosol/captured_image.jpg";
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK) {
        Log.i("uri-data", "Uri: " + mUri.toString());


        mBitmap = getBitmapFromUri(mImageView,BildActivity.this,mUri);


        mImageView.setImageBitmap(mBitmap);
        mImageView.setScaleType(ImageView.ScaleType.CENTER_CROP);

    }

}

Provider in res/xml

    <paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/> </paths>

Any Idea where the Problem Occurs?

Answer 1

The provider tag is outside of the application tag in the manifest file .

You should add it inside the <application></application> tag

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