android - VerifyPerSourceInstallationConsentInstallTask​​.f(2)：包名 null 不是已安装的包

Question

在 android 6.0 中，我想有意安装 apk。在 logcat中说PackageInstallergotto be installed app和. 但我有一个错误，。 我要求阅读许可，仍然没有警告。package namecallerPackageName
VerifyPerSourceInstallationConsentInstallTask.f(2): Package name null is not an installed package

这是我的代码：

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button button = findViewById(R.id.button);
        textView = findViewById(R.id.txt);


        button.setOnClickListener(this);


    }


    @Override
    public void onClick(View v) {
        installApp(this);

    }

    public static void installApp(Activity context) {
        String filePath = Environment.getExternalStorageDirectory() + "/app.apk";

        Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
        intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);//add read and write permissions
        }
        intent.setDataAndType(GetPathUri(context, filePath), "application/vnd.android.package-archive");
        context.startActivity(intent);

    }

    public static android.net.Uri GetPathUri(Context context, String filePath) {
        android.net.Uri uri;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            String packageName = context.getPackageName();
            uri = FileProvider.getUriForFile(context, packageName + ".fileProvider", new File(filePath));
        } else {
            uri = android.net.Uri.fromFile(new File(filePath));
        }

        return uri;
    }
}

这是logcat：
