android - 我的应用程序崩溃了 Google 服务框架 x_X

Question

我的应用每隔 x 时间检查一次未接来电。一切正常，但一段时间后它会使 Google 服务框架 (com.google.process.gapps) 崩溃并显示强制关闭对话框。所以我插上电话并查看 LogCat，并在检查未接来电时发现此错误。

E/IMemory(11481): cannot dup fd=1023, size=1048576, err=0 (Too many open files)

E/IMemory(11481): cannot map BpMemoryHeap (binder=0x8b06f0), size=1048576, fd=-1 (Bad file number)

E/JavaBinder(11481): * Uncaught remote exception! (Exceptions are not yet supported across processes.)

这是我检查未接来电的方式

String[] projection = { CallLog.Calls.TYPE, CallLog.Calls.NEW };
                     String where = CallLog.Calls.TYPE + "=" + CallLog.Calls.MISSED_TYPE + " AND " + CallLog.Calls.NEW + "=1";

Cursor c = this.getContentResolver().query(CallLog.Calls.CONTENT_URI, projection, where, null, null);

if(c != null) {
     c.moveToFirst();
     int mMissedCallCount = c.getCount();
...
}

所以看看 LogCat，是光标导致了问题。我在这里做错了什么吗？另外，“打开的文件太多”是什么意思？我还没有打开任何文件 - 无论如何我都知道......

您似乎从未在 Cursor 上调用 c.close()。在处理光标后尝试添加它，看看它是否解决了问题。
