Android - write to a file . Can't find the file - stream

Question

I'm new to android, so this might be prety basic.
I'm trying to write data into a file, yet I can not find the file in the device.
I'm trying to get the file in the following directory:
"Computer\Nexus 5\Internal storage\Android\data\application name"
I have tried different method but none of them has worked:
FileOutputStream stream;
try {
stream = openFileOutput(filename,Context.MODE_APPEND | Context.MODE_WORLD_READABLE);
stream.write(string.getBytes());
stream.close();
}catch(IOException e){
}}
and
String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/Android/data/" + packageName + "/files/";
try {
boolean exists = (new File(path )).exists();
if (!exists) {
new File(path ).mkdirs();
}
// Open output stream
FileOutputStream fOut = new FileOutputStream(path + filename,true);
// write integers as separated ascii's
fOut.write((Integer.valueOf(content).toString() + " ").getBytes());
// Close output stream
fOut.flush();
fOut.close();
} catch (IOException e) {
e.printStackTrace();
}
I have added the permission in the manifest :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.proLeague"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_MEDIA_STORAGE"/>
<group gid="sdcard_rw" />
<group gid="media_rw" />
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<application
android:allowBackup="true"
android:debuggable= "true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I thought maybe the file is logged properly but I need to pull it out from the ADB, is that possible?

Answer 1

I had manage to solve my issues on my own :
Evantually the code was fine, the problem was that on my nexus 5 phone I need to reboot the phone before I search for new files in the flash storage.
I saw in some blogs it is pretty common.
