问题
I want to combine 2 android projects together in such a way that when an button is pressed from one activity (of 1st project ) it should start my activity from (2nd project) both the projects are fully functional applications.. it is just that they were developed in parts i tried a lot of searches entire but ended up being frustated can someone provide me with a simple way to do so
the activity i am trying to call is
MainActivity.java from 2nd project when a button is pressed from activity in first project
i want to combine the projects together..so that i can export it as a single apk...
回答1:
The answer depends on what you intend to do with the projects.
If you wish to merge the project into a single app , at least one of them should be set as an android library , and another project should use it . This way , the merged projects would be able to recognize each other .
If you wish to have 2 apps and not a single app , each activity that you wish to access from another activity should have a special definition in the manifest (using intent filter) of how to open it , as it's not the default behavior .
回答2:
If all you need is to show a new MainActivity instance you need to declare an intent-filter in your "2nd project" manifest:
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="your.package.here.MainActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Then create an intent with the same action string in your first project:
Intent intent = new Intent("your.package.here.MainActivity");
startActivity(intent);
