I was trying to open file manager by passing the path of the folder that i specifically want to open.

But the app keeps crashing. below i hava attached the code, manifest file and the crash log.

If you are able to solve the problem do comment your suggestions.

CODE:

 Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
 Uri fileUri = FileProvider.getUriForFile(getApplicationContext(), BuildConfig.APPLICATION_ID+".fileprovider",folder);

 intent.setDataAndType(FileProvider.getUriForFile(getApplicationContext(), BuildConfig.APPLICATION_ID+".fileprovider",folder),"file/*");
 intent.setFlags(Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION);
 startActivityForResult(intent);

Manifest file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 package="com.example.fileprovideropenfile">

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />


 <application
 android:allowBackup="true"
 android:icon="@mipmap/ic_launcher"
 android:label="@string/app_name"
 android:roundIcon="@mipmap/ic_launcher_round"
 android:supportsRtl="true"
 android:theme="@style/AppTheme"
 tools:ignore="GoogleAppIndexingWarning">

 <activity android:name=".MainActivity">
 <intent-filter>
 <action android:name="android.intent.action.MAIN" />

 <category android:name="android.intent.category.LAUNCHER" />
 </intent-filter>
 </activity>
 <provider
 android:name="android.support.v4.content.FileProvider"
 android:authorities="$applicationId.fileprovider"
 android:exported="false"
 android:grantUriPermissions="true">
 <meta-data
 android:name="android.support.FILE_PROVIDER_PATHS"
 android:resource="@xml/file_paths">
 </meta-data>
 </provider>
 </application>

</manifest>

XML file:

<external-path name="file" path="com.example.fileprovideropenfile/"/>

Your comments are much welcomed. Please help me solving this problem.

Intent intent = new Intent(Intent.ACTION_GET_CONTENT); Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath() + "/myFolder/"); intent.setDataAndType(uri,"*/*"); startActivity(Intent.createChooser(intent, "Open folder")); 

No changes in android manifest file. Please use above code only.
