生成的“app-release.apk”……在我的设计中不起作用，但“app-debug.apk”运行良好，

更新:

转到我的应用程序的先前版本后:

在我的 MainActivity 中我有这个字符串:

public class MainActivity extends ActionBarActivity {

 @Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

     final String PREFS_NAME = "MyPrefsFile";

     SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);

     if (settings.getBoolean("my_first_time", true)) {
         //the app is being launched for first time, do something

         TeamModel pm;
         DBHelper db;

         String teamNames1= "Los Angeles Lakers";
         String teamOpponent1= "Golden State Warriors";
         String teamDate1= "2015-03-16 22:30";

         String teamNames2= "Atlanta Hawks";
         String teamOpponent2= "Sacramento Kings";
         String teamDate2= "2015-03-16 20:00";

         .
         .

         String teamNames348= "Charlotte Hornets";
         String teamOpponent348= "Utah Jazz";
         String teamDate348= "2015-03-16 21:00";


         db = new DBHelper(getApplicationContext());
         db.getWritableDatabase();
         pm = new TeamModel();



         pm.teamname=       teamNames1;
         pm.teamopponent=teamOpponent1;
         pm.teamdate=        teamDate1;

         db.addTeam(pm);

         pm.teamname=       teamNames2;
         pm.teamopponent=teamOpponent2;
         pm.teamdate=        teamDate2;

         db.addTeam(pm);
         .
         .
         pm.teamname=       teamNames348;
         pm.teamopponent=teamOpponent328;
         pm.teamdate=        teamDate348;

         db.addTeam(pm);

         Log.d("Comments", "First time");
         settings.edit().putBoolean("my_first_time", false).commit();

从此 Activity 中删除字符串 1 到 107(teamNames、teamOpponent、teamdate)后，应用程序在我的设备上运行良好

为了解释更多，我的 MainActivity 变成了:

public class MainActivity extends ActionBarActivity {

 @Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

     final String PREFS_NAME = "MyPrefsFile";

     SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);

     if (settings.getBoolean("my_first_time", true)) {
         //the app is being launched for first time, do something

         TeamModel pm;
         DBHelper db;

         String teamNames107= "Los Angeles Lakers"; !!!
         String teamOpponent107= "Golden State Warriors"; !!!
         String teamDate107= "2015-03-16 22:30"; !!!

         String teamNames108= "Atlanta Hawks";
         String teamOpponent108= "Sacramento Kings";
         String teamDate108= "2015-03-16 20:00";

         .
         .

         String teamNames348= "Charlotte Hornets";
         String teamOpponent348= "Utah Jazz";
         String teamDate348= "2015-03-16 21:00";


         db = new DBHelper(getApplicationContext());
         db.getWritableDatabase();
         pm = new TeamModel();



         pm.teamname=       teamNames107;
         pm.teamopponent=teamOpponent107;
         pm.teamdate=        teamDate107;

         db.addTeam(pm);

         pm.teamname=       teamNames108;
         pm.teamopponent=teamOpponent108;
         pm.teamdate=        teamDate108;

         db.addTeam(pm);
         .
         .
         pm.teamname=       teamNames348;
         pm.teamopponent=teamOpponent328;
         pm.teamdate=        teamDate348;

         db.addTeam(pm);

         Log.d("Comments", "First time");
         settings.edit().putBoolean("my_first_time", false).commit();

怎么了？我怎样才能在不删除字符串的情况下解决这个问题？

当我尝试通过终端在我的设备上安装 app-release.apk 时我的错误日志:

Failure [INSTALL_FAILED_DEXOPT]  

当我尝试在“build variant: release”的设备上安装时，我得到了这个:

Installation failed since the device possibly has stale dexed jars that don't match the current version (dexopt error). In order to proceed, you have to uninstall the existing application. WARNING: Uninstalling will remove the application data! Do you want to uninstall the existing application?

在确定或取消时我得到:

Failure [INSTALL_FAILED_DEXOPT]

注意:在模拟器上一切正常

最佳答案

如果您使用的是模拟器，请关闭模拟器。运行 AVD Manager 并点击编辑按钮删除模拟器的数据。 在 android studio 中，您可以通过右键单击模拟器轻松删除模拟器。

如果它在您的真实设备中。然后转到设置>>应用程序>> 然后搜索您的应用并做两件事。

1. 清除数据
2. 卸载

现在运行您的应用程序。它应该有效。
