启动我的应用程序后,模拟器告诉我,不幸的是它已经停止了。我之前遇到了同样的错误,然后我修复了它,但是在添加启动活动之后我又遇到了这个问题。

public class perv extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(com.gosha.bux.R.layout.pervy);
Thread timer = new Thread(){

只需这样做
Intent i = new Intent(getapplicationcontext(),
TARGET_Activity.class);
startActivity(i);
并在清单
<activity
android:name="com.your.packagename.TARGET_Activity"
android:screenOrientation="portrait" >
</activity>
答案 1 :(得分:1)
在你的依赖编译中:
'com.android.support:multidex:1.0.0'
并设置multiDexEnabled true
。
YourApplication
:extends MultiDexApplication
添加:
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
最后在AndroidManifest
声明:android:name=".MyApplication"
答案 2 :(得分:0)
Intent openMainActivity = new Intent("com.gosha.bux.MAINACTIVITY");
startActivity(openMainActivity);
是错误的,而是使用:
Intent openMainActivity = new Intent(this, YourMainActivity.class);
答案 3 :(得分:0)
在Public class perv中你写了这个:
的setContentView(com.gosha.bux.R.layout.pervy);
你写了pervy而不是perv,这可能会导致这个错误
