Question

我正在开发一个安全应用程序，因为我需要捕获或检测用户输入的错误密码。我在android studio上使用API级别22进行此操作。但什么也没发生。它显示错误。

"Installing com.example.sourav.myfirstapp DEVICE SHELL COMMAND: pm
install -r "/data/local/tmp/com.example.sourav.myfirstapp"  pkg:
/data/local/tmp/com.example.sourav.myfirstapp Failure
[INSTALL_PARSE_FAILED_MANIFEST_MALFORMED]"

以下是我的代码的详细信息：

主要活动 -

 public class AdminReceiver extends DeviceAdminReceiver {
    @Override
    public void onPasswordChanged(Context ctxt, Intent intent) {
    DevicePolicyManager mgr=
            (DevicePolicyManager)ctxt.getSystemService(Context.DEVICE_POLICY_SERVICE);
    int msgId;

    if (mgr.isActivePasswordSufficient()) {
        msgId=R.string.compliant;
    }
    else msgId = R.string.not_compliant;

    Toast.makeText(ctxt, msgId, Toast.LENGTH_LONG).show();
}

@Override
public void onPasswordFailed(Context ctxt, Intent intent) {
    Toast.makeText(ctxt, "u will never break!", Toast.LENGTH_LONG)
            .show();
    String tag="tag";
    Log.v(tag,"this massage from error" );
}

@Override
public void onPasswordSucceeded(Context ctxt, Intent intent) {
    Toast.makeText(ctxt, "good u enterd", Toast.LENGTH_LONG)
            .show();
    String tag="tag";
    Log.v(tag, "this massage from success");
}
}`
