NPE in KeenClient.getKeenCacheSubDirectories() when getKeenCacheDirectory() returns an invalid directory #7

Closed dkador closed 10 years ago

dkador commented 10 years ago

The bug I found is a NullPointerException on line 318 of KeenClient.java. Working backwards, that means that getKeenCacheSubDirectories() returns null, which happens because getKeenCacheDirectory() returns an invalid directory.

To fix the bug, I run the following code before calling KeenClient.upload():

java.io.File keenDir = new java.io.File(context.getCacheDir(), "keen");
if(!keenDir.exists()) {
    keenDir.mkdir();
}

Wrong project. This should be in KeenClient-Android.
