Question

我偶尔会在SyncAdapter类中抛出以下异常。我认为我正在关闭所有游标。是否有任何其他解释为什么抛出此异常？或者我绝对错过了某个地方的cursor.close（）？

Fatal Exception: android.database.CursorWindowAllocationException: Cursor window could not be created from binder.

通过将以下代码段添加到我的应用程序onCreate（），我能够找到其他可关闭的泄漏：

    if(BuildConfig.DEBUG){
        StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
                .detectLeakedSqlLiteObjects()
                .detectLeakedClosableObjects()
                .penaltyLog()
                .build());
    }

它记录了一些我能够解决的漏洞。这是一个非常有用的开发工具。
