i am developing on Asus nexus 7, and i am writing data to file on the internal storage. at run time i receive the below posted logcat output which casese the App
to terminate.
the same App tested against Samsung galaxx note 3 and it worked fine without crashing
i want to know how to fix these error when tesing against Asus nexux 7 and why that is happening.
Note: the required permission for writing on the external storage is added
please let me know what i am missing in the code
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

01-11 18:28:40.280 I/ACES: Service is still running
Its Working fine in android lower versions.
As the Problem shows: You need to add internet access permission in the app.
<manifest xlmns:android...>
...
<uses-permission android:name="android.permission.INTERNET" />
<application ...
</manifest>
And at last when app asks for internet access in popup allow the app to use internet!
while updating app from playstore I'm getting the error..

also I've added in my AndroidManifest.xml following lines:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
but still getting the same exception
Simple solution: set your target SDK back to 22
Clean Solution: Request the Runtime Permissions
Check this out for more informations.
I'm trying to use JCodec to get all the frames from an MP4 on my emulator. I have the following permissions in my manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" />
The file through my adb shell looks like this:
root#generic_x86_64:/sdcard/Download # pwd
/sdcard/Download
root#generic_x86_64:/sdcard/Download # ls -la
-rwxrwx--x root sdcard_rw 19967250 2015-10-12 16:39 Hummingbird.MP4
I've tried doing a chmod 777 Hummingbird.MP4, but that doesn't change the last set of permissions for some reason?
The following code produces the exception below.
String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
String fn = baseDir + "/Download/Hummingbird.MP4";
// test dir to make sure I'm in right place
String dir = baseDir + "/Download";
File fDir = new File(dir);
Log.i("TAG", "fDir.isDir()=" + fDir.isDirectory()); // this is true
fileMp4 = new File(fn);
try {
ch = NIOUtils.readableFileChannel(fileMp4); // line 220 in trace below
} catch (FileNotFoundException e) {
e.printStackTrace();
}
I also did a fileMp4.exists() which returns true.

See any problems with this code/configuration?
I was able to get the 'NIOUtils.readableFileChannel(fileMp4)' statment working by creating the file at /data/tmp/Hummingbird.MP4 (adb push). Not sure if it's something about /sdcard and its symbolic links, or maybe I just needed to make sure all the directories and file were owned by system instead of root.
Anyway, I'm now on to other issues and problems decoding the MP4 but that's another story.
