A SQLiteConnection object for database '/data/data/.../databases/....db' was leaked!

详细异常：

A SQLiteConnection object for database ‘/data/data/.../databases/....db‘ was leaked!  Please fix your application to end transactions in progress properly and to close the database when it is no longer needed

明显是数据库操作异常，数据库对象被锁，明确告诉你对象长久不用需要关闭。

改正：获取数据库对象改成单例模式，项目运行中只保证唯一一个对象即可。如下：

private static XXXXSQLHelper mInstance = null;

public synchronized static XXXXSQLHelper getInstance(Context context) {
if (mInstance == null) {
mInstance = new XXXXSQLHelper(context);
}
return mInstance;
};

调用如下：

public XXXXDBUtil(Context context) {
mSQLiteDatabase = XXXXSQLHelper.getInstance(context)
.getWritableDatabase();
}

注意：此时数据库对象是唯一实例了，不需要close了，如果close掉，将会出现对象已关闭的严重异常，导致程序崩溃。
