What is the method for Android to call the application installation interface? for this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

1. First add permissions to AndroidManifest.xml (manifest configuration file)

two。 Create a xml package under res to add a path to the manifest configuration file later

3. Create a xml file under the xml package

Because I am using external storage (path / storage/emulated/0/Android/data/ package name / files/ name) for the location of the software installation package here, I choose to use external-files-path

Other storage paths are in the following format

(1) files-path:

Corresponding physical path: getFilesDir (

Corresponding specific path: / data/user/0/ package name / files

(2) cache-path:

Corresponding physical path: getCacheDir ()

Corresponding specific path: / data/user/0/ package name / cache

(3) external-path:

Corresponding physical path: Environment.getExternalStorageDirectory ()

Corresponding specific path: / storage/emulated/0

(4) external-files-path:

Corresponding physical path: getExternalFilesDir ("first name")

Corresponding to specific path: / storage/emulated/0/Android/data/ package name / files/ name

(5) external-cache-path:

Corresponding physical path: getExternalCacheDir ()

Corresponding specific path: / storage/emulated/0/Android/data/ package name / cache

4. Add configuration in AndroidManifest.xml (manifest configuration file)

5. Add implicit intent and permission codes to the java file

Private void iniAPK () {Intent intent = new Intent (Intent.ACTION_VIEW); intent.addFlags (Intent.FLAG_ACTIVITY_NEW_TASK); if (Build.VERSION.SDK_INT > = Build.VERSION_CODES.N) {/ / 7.0+ above Uri apkUri = FileProvider.getUriForFile (this, "this is the unique name given to the manifest configuration file .fileprovider", file) Intent.addFlags (Intent.FLAG_GRANT_READ_URI_PERMISSION); intent.setDataAndType (apkUri, "application/vnd.android.package-archive");} else {intent.setDataAndType (Uri.fromFile (file), "application/vnd.android.package-archive");} this.startActivity (intent);}

What is Android? Android is a free and open source operating system based on the Linux kernel, mainly used in mobile devices, such as smartphones and tablets, led and developed by Google and the Open Mobile Alliance.
