在android studio中,build variant设置为"debug"模式,我发现了apk的两个输出

• APP-debug.apk
• 应用程序调试,unaligned.apk

这些文件之间有什么区别？

我有一个ContentProvider,它有两个表1. OnlineContacts2 AllContacts.然后我有一个方法,我查询两个表并分别得到他们的结果cursors.然后使用并列出一个列表加入他们.将此列表传递给我,我正在填充我的.喜欢 :CursorJoinerContactsCustomAdapter extending BaseAdapterlistview

public static List<Contact> getContacts(Context context){
    List<Contact> contactList = new ArrayList<Contact>(); 

// Getting First Cursor
    String URL = xyz;
    Uri baseUri1 = Uri.parse(URL);
    String[] select = xyz; 
    String where =xyz; 
    Cursor cursor =  context.getContentResolver().query(baseUri1, select, where, null, "pid");

// Getting 2nd Cursor
    Uri baseUri = xyz; 
    String[] projection =xyz; 
    String selection =xyz; 
    String[] selectionArgs = null;
    String sortOrder = xyz;

    if (state == null) {

        phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
        Intent serviceIntent = new Intent(context, NarenService.class);
        context.startService(serviceIntent);
        Toast.makeText(context, "Calling..to  " + phoneNumber, Toast.LENGTH_SHORT).show();
    }
  }
}

服务

public class NarenService extends Service implements LocationListener {
SQLiteDatabase db;
double lat, lon;
LocationManager locationManager;
String provider;

DataProvider dataProvider;
Cursor cursor;
private static final String TAG = "NarenService";

@Override …
