Project Layout:

<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" xmlns: tools = "http://schemas.android.com/tools" android: layout_width = "match_parent" android: layout_height = "match_parent" android: orientation = "vertical" tools: context = ". mainActivity "> <EditText android: id =" @ + id/et_path "android: layout_width =" fill_parent "android: layout_height =" wrap_content "android: text = "Enter the apk path"/> <Button android: onClick = "click" android: layout_width = "fill_parent" android: layout_height = "wrap_content" android: text = "Install"/> </LinearLayout>

The logic code is as follows:

public class MainActivity extends Activity {    private EditText et_path;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        et_path = (EditText) findViewById(R.id.et_path);    }    public void click(View view) {        String path = et_path.getText().toString().trim();        /*         * <action android:name="android.intent.action.VIEW" /> <category         * android:name="android.intent.category.DEFAULT" /> <data         * android:scheme="content" /> <data android:scheme="file" /> <data         * android:mimeType="application/vnd.android.package-archive" />         */        Intent intent = new Intent();        intent.setAction("android.intent.action.VIEW");        intent.addCategory("android.intent.category.DEFAULT");        intent.setDataAndType(Uri.fromFile(new File(path)), "application/vnd.android.package-archive");        startActivity(intent);    }}

First, add the installer permission to AndroidManifest. xml:

<Uses-permission android: name = "android. permission. INSTALL_PACKAGES"/>
