应用程序在设备中崩溃，但在模拟器中未崩溃

Question

我在模拟器上运行了该应用程序，它运行良好，但是当我将其安装在设备中时，它崩溃了。

这是导致崩溃的代码

c1.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                if ( c1.isChecked() )
                {
                    SQLHandler check = new SQLHandler(StartMoving.this);
                    check.open();
                    check.updateTodo(currentMove, "sortandpurge", "Done");
                    check.close();
                }else{
                    SQLHandler check = new SQLHandler(StartMoving.this);
                    check.open();
                    check.updateTodo(currentMove, "sortandpurge", "Not Done");
                    check.close();
                }
            }
        });

该代码的作用是，如果单击该复选框，则将更新数据库。

public void updateTodo(String todoMove, String todoName, String todoValue){
        ContentValues cv = new ContentValues();
        cv.put(todoName, todoValue);
        ourDatabase.update(DATABASE_TABLE4, cv, KEY_TODOMOVE + "='" + todoMove + "'", null);
    }

但是以某种方式应用程序在设备中崩溃，但在模拟器中却没有崩溃

Answer 1

我发现了问题，看来我将列之一设置为整数而不是应设置为文本，这让我很愚蠢。

Answer 2

当发生ANR（应用程序无响应）情况时，dalvik将发送“ threadid = 3：对信号3作出反应”消息。 您可以在/data/anr/trace.txt文件中找到详细信息。
