java.lang.SecurityException：Permission Denial：在另一个应用程序上启动Intent

Question

我正在尝试从我的应用程序中打开另一个应用程序（1mg）活动。我通过反编译apk从清单文件中找到了另一个应用程序的类名和包名（1mg）。我究竟做错了什么？此外，如果您还可以帮我检查是否安装了应用程序（1mg），如果没有安装，则应该打开www.1mg.com

Answer 1

使用：

解决了这个问题

Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.setComponent(new ComponentName("com.aranoah.healthkart.plus","com.aranoah.healthkart.plus.pharmacy.search.autocomplete.SearchActivity"));
        startActivity(intent);

此外，它还要求您添加正确的类名。这一切都取决于你通过另一个应用程序的清单文件多少，并执行命中和试用方法，并希望它可能很快就会解决。
