Android SDK crash

Hongbin L.

Hi. I have implemented Dropbox API in my android app.

After released the app to public, I got a number of crash report from the Dropbox SDK. No sure what is the root cause.

 

The issue seems to happen on a varieties of devices. Please help! Thank you so much.

Could you tell us what version of what SDK you're using?

I think based on the stack that you're using some version of the Core API (v1) Android SDK, but it would help to know exactly which version.

In the current code for onNewIntent, this is the only call I see to getPath(), which sure looks like it's guarded against null pointer exceptions.

 } else {
    // Web auth.
    Uri uri = intent.getData();
    if (uri != null) {
        String path = uri.getPath();

One quick way to check which version you're using is to look at SdkVersion.java.

EDIT: If using a JAR file, the version number should be in the name of the file.
