请在开始本活动
帮助。
意图splashActivity =新意图(android.intent.action.Splash);
没有 - 不 - 不!它应该给
意图splashActivity =新意图(背景下,Splash.class);
如果您使用的行动 - 这似乎是你想要某种行动的活动,例如,在浏览器中查看网页。
在你的情况,你必须使用具体的活动,并将其设置为意图
<作用机器人:名字=android.intent.action.MAIN/>
这个动作是不是为你的应用程序,它是需要Android的发射器,在您的应用程序来启动它找到活动
I have this Activity
defined in my AndroidManifest.xml
:
<activity
android:name=".Splash"
android:label="@string/app_name"
android:noHistory="true" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
When I am trying to call it in this way:
Intent splashActivity = new Intent("android.intent.action.Splash");
mainAppContext.startActivity(splashActivity);
I get:
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.Splash }
And when I try to start it in this way:
Intent splashActivity = new Intent("android.intent.action.MAIN ");
mainAppContext.startActivity(splashActivity);
It open a Complete action using
dialog with many options there like play store etc.
Please help in starting this Activity
.
Intent splashActivity = new Intent("android.intent.action.Splash");
No-no-no! It should to
Intent splashActivity = new Intent(context, Splash.class);
If you use action - it seem that you want activity for some type of action, for example, view webpage on browser. In your situation you have to use concrete activity and set it to intent
<action android:name="android.intent.action.MAIN" />
this action is not for your app, it is needed to android's launcher, that find activity in your application to launch it
