Here is my code and the error below. I get an error in the logs saying Unable to create external files directory.
String downloadURL = getString(R.string.download_URL);
Uri uri = Uri.parse(downloadURL);
DownloadManager.Request request = new Request(uri);
request.setAllowedNetworkTypes(Request.NETWORK_WIFI | Request.NETWORK_MOBILE);
request.setAllowedOverRoaming(false);
request.setTitle("Android Jelly Bean's Pic Download");
request.setDescription("Android Jelly Beans Pic Download using Download Manager");
request.setDestinationInExternalFilesDir(getApplicationContext(),
Environment.DIRECTORY_DOWNLOADS, "abc.png");
downloadReference = dm.enqueue(request);
The line which has the error is
request.setDestinationInExternalFilesDir(getApplicationContext(),
Environment.DIRECTORY_DOWNLOADS, "abc.png");

In order to save/write the data into file or create/remove directories, you must have to set "usage" permission in manifest file.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Sample : Android DownloadManager
You can you try something like:
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + fileName);
Instead of:
request.setDestinationInExternalFilesDir(Context, Type, Path)

I just started developing with parse. I downloaded the android ParseLoginUI and the sample apps. Two things I had done to be able to start the app: for ParseLoginUI add a reference to the FacebookSDK and copy the "bolts-android-1.1.2.jar" file from the FacebookSDK libs folder to the ParseLoginUI lib folder.
The ParseLoginSampleBasic runs, the first screen comes up, but when I click on the Log in button , this exception comes up:

I can't find any documentation that states what is the reason of this exception.
EDIT:
After reading ContentResolver documentation I find out null pointer cause by getcontentService().
It could be different for you, but for me this was caused because I had a null mAccount object. I had incorrectly assumed that if AccountManager.addAccountExplicitly returned false then there had been a fatal error, so was returning a null Account from my CreateSyncAccount function in that situation.

I am developing an app for all android devices. It is working good on all device and I tested it on Samsung Galaxy S1, Galaxy Nexus, Motorola Xoom, HTC One and also on Amazon Kindle Fire.
It runs perfectly on all devices but when i tried using it on Nexus 7, it crashes and in log it says Out of Memory Error. I tried using System.gc(); in Activity#onPause() method but in vain. There are alternative drawables and layouts exist in app.
Please help me to resolve this issue. This issue is only specific to Nexus 7.
Below is stacktrace:

Ya i had faced this issue too but not found a valid solution but you can try using android:largeHeap="true" in manifest at application level

The Android project uses maven but creating a new one without maven the problem persists and shows the same message.
Any suggestions to fix this problem?
Thanks
At some point (probably after ver 15), the libraries you use must be placed in the "libs" folder. Try placing a copy of your libraries there and retry

I’m having problems with my Sudoku application. I plugged in all the code to have my application remember the current position. Now when I run the application and I try to either start a new game or continue my Sudoku application says:
Sorry the application Sudoku (process org.example.sudoku) has stopped unexpectedly. Please try again.
It hasn’t done this in the past yet and I’m confused on where to go from here. I took a look at the logcat but I’m not sure what I should look for and how to fix it. Here is the logcat below

Any help would be greatly appreciated. Thank you

You need to look at line 104 of Game.java as it seems it may be the cause of a NullPointerException
Your error of interest is:
12-05 14:48:15.295: ERROR/AndroidRuntime(304): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{org.example.sudoku/org.example.sudoku.Game}: java.lang.NullPointerException
Usual error - your intent is not in the Manifest.xml
