Android实现用代码简单安装和卸载APK的方法

public class TestInstallAPK extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); // this.unInstallFile(); installFile(); } /** * install APK code */ private void installFile(){ Intent intent = new Intent(Intent.ACTION_VIEW);  intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  intent.setAction(android.content.Intent.ACTION_VIEW);//  String type = getMIMEType(f);//  intent.setDataAndType(Uri.fromFile(f), type); intent.setDataAndType(Uri.parse("file://" + "/sdcard/Android_gc.apk"),  "application/vnd.android.package-archive"); this.startActivity(intent); } /** * uninstall APK code */ private void unInstallFile(){ Uri uri=Uri.parse("package:com.gameclient"); Intent intent = new Intent(Intent.ACTION_DELETE,uri); this.startActivity(intent); }}
