| If you want install application programmatically in Android 10, You need to give permission to install app for your application | |
| ============================================================================== | |
| Steps 1: Give permission in Manifest | |
| ============================================================================== | |
| <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" /> | |
| <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> | |
| <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> | |
| ============================================================================== | |
| Step 2: Write provider in Android Manifest | |
| ============================================================================== | |
| <provider | |
| android:name="androidx.core.content.FileProvider" | |
| android:authorities="${applicationId}.provider" | |
| android:exported="false" | |
| android:grantUriPermissions="true"> | |
| <meta-data | |
| android:name="android.support.FILE_PROVIDER_PATHS" | |
| android:resource="@xml/provider_paths" /> | |
| </provider> | |
| ============================================================================== | |
| Step 3: Create file in XML folder named as provider_paths.xml and write | |
| ============================================================================== | |
| <?xml version="1.0" encoding="utf-8"?> | |
| <paths xmlns:android="http://schemas.android.com/apk/res/android"> | |
| <external-path | |
| name="files_root" | |
| path="Android/data/${applicationId}" /> | |
| <external-path | |
| name="external_files" | |
| path="." /> | |
| </paths> | |
| ============================================================================== | |
| Step 4: Give runtime permission for apk installation and storage permissions | |
| ============================================================================== | |
| //installtion permission | |
| if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { | |
| if (!getPackageManager().canRequestPackageInstalls()) { | |
| startActivityForResult(new Intent(Settings.ACTION_MANAGE_UNKNOWN_APP_SOURCES).setData(Uri.parse(String.format("package:%s", getPackageName()))), 1234); | |
| } else { | |
| } | |
| } | |
| //Storage Permission | |
| if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { | |
| ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE}, 1); | |
| } | |
| if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { | |
| ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1); | |
| } | |
| ============================================================================== | |
| Step 5: Call install apk function | |
| ============================================================================== | |
| void installAPK(){ | |
| String PATH = Environment.getExternalStorageDirectory() + "/" + "apkname.apk"; | |
| File file = new File(PATH); | |
| if(file.exists()) { | |
| Intent intent = new Intent(Intent.ACTION_VIEW); | |
| intent.setDataAndType(uriFromFile(getApplicationContext(), new File(PATH)), "application/vnd.android.package-archive"); | |
| intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); | |
| intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); | |
| try { | |
| getApplicationContext().startActivity(intent); | |
| } catch (ActivityNotFoundException e) { | |
| e.printStackTrace(); | |
| Log.e("TAG", "Error in opening the file!"); | |
| } | |
| }else{ | |
| Toast.makeText(getApplicationContext(),"installing",Toast.LENGTH_LONG).show(); | |
| } | |
| } | |
| Uri uriFromFile(Context context, File file) { | |
| if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { | |
| return FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file); | |
| } else { | |
| return Uri.fromFile(file); | |
| } | |
| } |
