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.
