安装:
String str = "/CanavaCancel.apk"; String fileName = Environment.getExternalStorageDirectory() + str; Intent intent = new Intent(Intent.ACTION_VIEW); intent.setDataAndType(Uri.fromFile(new File(fileName)), "application/vnd.android.package-archive"); startActivity(intent);
卸载:
Uri packageURI = Uri.parse("package:com.demo.CanavaCancel");
Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI);
startActivity(uninstallIntent);
Environment拥有一些可以获取环境变量的方法
package:com.demo.CanavaCancel 这个形式是 package:程序完整的路径 (包名+程序名).
