I recieve from google play msg that my app crash, in the msg
java.lang.NullPointerException
at android.webkit.WebViewDatabase.initDatabase(WebViewDatabase.java:234)
at android.webkit.WebViewDatabase.init(WebViewDatabase.java:212)
at android.webkit.WebViewDatabase.access$000(WebViewDatabase.java:40)
at android.webkit.WebViewDatabase$1.run(WebViewDatabase.java:193)
I don't find in google or in stackoverflow similar probloem so I dont know why this crach, but I know that cause by webview.
Looks to be the same as this issue here (plus potential workaround):
https://code.google.com/p/android/issues/detail?id=35204
I found the code for WebViewDatabase here (it's not exactly the same version, but there is enough context to get the picture):
http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.1_r1/android/webkit/WebViewDatabase.java#WebViewDatabase.initDatabase%28android.content.Context%29
If you look at the code for initDatabase(), there is a potential NPE on the line that I marked with "****". Note that the following line checks for NULL, so it looks to be a bit dumb:
private void initDatabase(Context context) {
try {
mDatabase = context.openOrCreateDatabase(DATABASE_FILE, 0, null);
} catch (SQLiteException e) {
// try again by deleting the old db and create a new one
if (context.deleteDatabase(DATABASE_FILE)) {
mDatabase = context.openOrCreateDatabase(DATABASE_FILE, 0,
null);
}
}
mDatabase.enableWriteAheadLogging(); ****
// mDatabase should not be null,
// the only case is RequestAPI test has problem to create db
if (mDatabase == null) {
mInitialized = true;
notify();
return;
