生成的“app-release.apk”...在我的设备上不起作用，但“app-debug.apk”工作正常，
Update:
转到我的应用程序的先前版本后：
in my MainActivity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();
从此活动中删除字符串 1 到 107（teamNames、teamOpponent、teamdate）后，应用程序在我的设备上运行良好
解释更多我的MainActivity became:
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 时出现错误日志：
Failure [INSTALL_FAILED_DEXOPT]
当我尝试在设备上安装“构建变体：发布”时，我得到了以下信息：
安装失败，因为设备可能具有与当前版本不匹配的陈旧 dexed jar（dexopt 错误）。为了继续，您必须卸载现有的应用程序。 警告：卸载将删除应用程序数据！ 您想卸载现有的应用程序吗？
在“确定”或“取消”上我得到：
Failure [INSTALL_FAILED_DEXOPT]
NB:在模拟器上一切都很好
If you are using Emulator then close the emulator. Run AVD Manager and Wipe data of the emulator clicking on edit button.
In android studio you can easily wipe you emulator by right clicking on the emulator.
如果它在您的真实设备中。然后去设置>>应用>>然后搜索您的应用程序并执行 2 件事。
现在运行您的应用程序。它应该有效。
