Question

我试图在手机上运行我的应用程序。但是当我在应用程序中进行此活动时，它只会崩溃。但它在4.0.3和模拟器上运行完美。我该怎么办？ +我只是将app_debug.apk文件发送到我的手机并使用手机而不是安卓工作室安装，因为AS没有看到我的设备

private static final int CM_DELETE_ID = 1;

    lvData.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

        public void onNothingSelected(AdapterView parentView) {

        }
    });

}

private void buttonClick()
{
    startActivity(new Intent("com.example.dc2.TEST5"));
}

public void onButtonClick(View view) {
    switch(view.getId())
    {
        case R.id.button: {
            buttonClick();

        }
    }
}

public void onCreateContextMenu(ContextMenu menu, View v,
                                ContextMenu.ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    menu.add(0, CM_DELETE_ID, 0, R.string.delete_record);
}


public boolean onContextItemSelected(MenuItem item) {
    if (item.getItemId() == CM_DELETE_ID) {
        AdapterView.AdapterContextMenuInfo acmi = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
        db.delRec(acmi.id);
        // обновляем курсор
        cursor.requery();
        return true;
    }
    return super.onContextItemSelected(item);
}

protected void onDestroy() {
    super.onDestroy();
    db.close();
}

这是我的logcat

Answer 1

我找到了答案......在我的数据库代码中我有

private static final String DB_CREATE =
    "create table " + DB_TABLE + "(" +
            COLUMN_ID + " integer primary key autoincrement, " +
            COLUMN_IMG + " integer, " +
            COLUMN_TXT + " text, " +
            COLUMN_DAY + " day, " +
            COLUMN_MONTH + " month, " +
            COLUMN_YEAR + " year, " +
            COLUMN_HOUR + " hour, " +
            COLUMN_MINUTE + " minute, " +
            ");";

＆＃34;分钟＆＃34;之后应该没有昏迷之前＆＃34;）;＆＃34;

Answer 2

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="abc.abc" android:versionCode="1" android:versionName="1.0" android:installLocation="auto">
    <uses-sdk android:minSdkVersion="10" android:targetSdkVersion="22" />
    <application android:label="abc" android:icon="@drawable/Icon"></application>
</manifest>

在 androidmanifest.xml 文件中使用 android：targetSdkVersion =＆＃34; 22＆＃34; for android 5.1.1。

应用程序不适用于android 4.4.4和5.1.1，但适用于4.0.3和模拟器
