this work in all device but not in >= android 7.0 Nought device
I just solve this problem on Nexus6p android N,you need grant permission to uri so the system camera can access the file wait crop temporarily,because of StrictMode Android N has do not support pass a file:Uri in an Intent extra anymore see Scheme Ban in N Developer Preview,we use FileProvider instead.here is my source code:
AndroidManifest.xml
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="dreamgo.corp.provider"
android:grantUriPermissions="true"
android:exported="false">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/filepaths"/>
</provider>
filepaths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="images" path="."/>
</paths>
MainActivity.java
Uri photoURI = FileProvider.getUriForFile(context, "dreamgo.corp.provider", file);
//grant uri with essential permission the first arg is the The packagename you would like to allow to access the Uri.
context.grantUriPermission("com.android.camera",photoURI,
Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setDataAndType(photoURI, "image/*");
//you must setup two line below
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 200);
intent.putExtra("return-data", true);
//you must setup this
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(intent, 1);
I got the solution.Posting my answer.

Have you added this in Manifest.xml??
<application
........
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
</application>
this has to be there in your manifest.. for effect in the naugut android 7.0.
Again you need to add provider_paths.xml file in xml.
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
Uri uri = FileProvider.getUriForFile(this, getPackageName() + Configs.FILE_PROVIDER_NAME, inFile);
Intent intent = new Intent("com.android.camera.action.CROP");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
intent.setDataAndType(uri, "image/*");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(outFile));
You should notice that the uri for EXTRA_OUTPUT should not be modified by FileProvider. And your paths.xml should like this
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_sd" path="."/>
<external-files-path name="external_app" path="."/>
<files-path name="files" path="."/>
<cache-path name="cache" path="."/>
Because you create crop file under getExternalFilesDir. So <external-files-path> is necessary.
Following solution works for me. I've tested with Gallery, Google drive, Photos etc.
Sample is in Kotlin language.
ImagePickUtils.kt
fun getImageUri(context: Context, contentURI: String): Uri {
var conUri = Uri.parse(contentURI)
var filePath = ""
if (DocumentsContract.isDocumentUri(context, conUri)) {
val wholeID = DocumentsContract.getDocumentId(conUri)
// Split at colon, use second item in the array
val id = wholeID.split(":".toRegex()).dropLastWhile { it.isEmpty() }.toTypedArray()[1]
val column = arrayOf(MediaStore.Images.Media.DATA)
// where id is equal to
val sel = MediaStore.Images.Media._ID + "=?"
val cursor = context.contentResolver.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
column, sel, arrayOf(id), null) ?: return conUri
val columnIndex = cursor.getColumnIndex(column[0])
if (cursor.moveToFirst()) {
filePath = cursor.getString(columnIndex)
}
cursor.close()
if (filePath.isNotEmpty()) {
filePath = filePath.replace(" ".toRegex(), "%20")
conUri = Uri.parse("file://$filePath")
}
}
return conUri
}
onActivityResult of Activity / Fragment:
if (data != null) {
val imagePath: Uri
if (data.data != null) {
val mImageUri = data.data
imagePath = getImageUri(this@HomeActivity, mImageUri.toString())
Log.i(TAG+" Image actual path", imagePath.toString())
}
}
Hope this would help you.
This worked for me like charm for Marshmallow as well as for 7.1.2 (Naugat)
- To pick image from camera, as described in this answer follow these steps from this blog:
Write code as described in this step for both, Marshmallow as well as for 7.1.2 (Naugat)
- To crop the image, if you want to use intent
com.android.camera.action.CROP(which is actually not recommanded but still many developer use), then you can call these methods with URI in old style. i.e.Uri.fromFile(file)
cropIntent.setDataAndType(Uri.fromFile(file), "image/*");
and
cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
along with other methods (please search how to call intent com.android.camera.action.CROP)
And, finally before calling startActivityForResult(cropIntent, CROP_ACTIVITY_CODE)
make sure to write this this...
if(Build.VERSION.SDK_INT>=24)
{
try
{
Method m = StrictMode.class.getMethod("disableDeathOnFileUriExposure");
m.invoke(null);
}
catch(Exception e)
{
e.printStackTrace();
}
}
That's it! I hope it helps someone.
