用1个APK安装多个安卓应用[英] Installing multiple android apps with 1 APK

问题描述

I have two separate apps. Currently I am able to install them separately. I wanted to find out how I can install them using a single APK.

I want to be able to have both apps still run independently of each other but I wanted to be able to package them together.

This way when a user goes to the google play store they see one app, but it actually install both the apps.

Thanks, Jeff

you can define 2 luncher activity in your manifest file like bellow the result is what you want:

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity"
        android:icon="@mipmap/ic_launcher">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".MainActivity2"
        android:icon="@mipmap/ic_launcher">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

You cannot just install two apps directly without showing the user, the thing that you can do is to create a new app in which you will put your 2 apk files in the "raw" folder inside build folder. And push them to open together, those app will show a dialog to user to ask about permissions and will be installed if user allows.

Here is the code to do that:

 for (int a=0;a<names.length;a++)
    {
        InputStream in = null;
        OutputStream out = null;
        try {
            in = getBaseContext().getResources().openRawResource(array[a]);  // Here "array" is actually and array holding the reference of apk files (eg. R.raw.firstApp)
            out = new FileOutputStream(Environment.getExternalStorageDirectory().getPath()+"/"+names[a]+".apk");  // Here "names" is an array holding the names of your apk files (eg. "firstApp")
            Log.e("Path" ,Environment.getExternalStorageDirectory().getPath());
            byte[] buffer = new byte[1024];
            int read;
            while((read = in.read(buffer)) != -1){
                out.write(buffer, 0, read);
            }
            in.close();
            in = null;
            out.flush();
            out.close();
            out = null;
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory().getPath()+"/"+names[a]+".apk")), "application/vnd.android.package-archive");
            startActivity(intent);
        }catch(Exception e){
            // deal with copying problem
        }
    }
