我正在制作可以卸载系统应用程序的应用程序。在查看完StackOverFlow的所有答案之后,我可以说其中99%是通过ADB和我认为有用的https://stackoverflow.com/a/34399068/9953518,现在已从Android O更改了。
根据本文https://medium.com/@quaful/the-changes-of-apk-install-location-since-android-oreo-e646d1b53c4d,现在无法导航到应用程序的特定文件夹,并且我们必须使用.sourceDir。我遇到的问题是在请求根目录并获取sourceDir之后,.apk文件不会卸载,如果确实存在,则在这种情况下不会卸载或删除完整的文件。我正在使用以下代码:
//appsSelected is the array with all the package names of the system apps selected to be uninstalled
case "uninstall":
for (int i = 0; i < appsSelected.size(); ++i) {
final int finalI = i;
Thread worker = new Thread(new Runnable() {
@Override
public void run() {
RootManager.getInstance().obtainPermission();
System.out.println("Public directory is "+ yup(appsSelected.get(finalI)));
runCommand("rm -rf "+ yup(appsSelected.get(finalI)) );
}
});
worker.start();
}
break;
这是返回filePath的功能:
String yup(String pack){
PackageManager m = getPackageManager();
PackageInfo p = null;
try {
p = m.getPackageInfo(pack, 0);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return p.applicationInfo.sourceDir;
}
最后是运行命令的函数:
public static void runCommand(String command) {
try {
Process chmod = Runtime.getRuntime().exec(command);
BufferedReader reader = new BufferedReader(
new InputStreamReader(chmod.getInputStream()));
int read;
char[] buffer = new char[4096];
StringBuffer output = new StringBuffer();
while ((read = reader.read(buffer)) > 0) {
output.append(buffer, 0, read);
}
reader.close();
chmod.waitFor();
String outputString = output.toString();
} catch (IOException e) {
throw new RuntimeException(e);
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
}
我具有root权限(“ su”命令)和所有必需的权限。
答案 0 :(得分:0)
首先,运行:
pm uninstall <package_name>
然后
rm -r <applicationinfo.sourceDir>
然后
rm -r <applicationinfo.publicSourceDir>
然后重新启动设备,并应卸载该应用程序。
注意:所有这些命令都应以root用户身份运行!
