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。
