IllegalAccessError only on Android 9 inside AsyncTask

Question

IllegalAccessError 仅在 Android 9 发生在 AsyncTask 函数期间

Android9 有什么事要做吗？其他版本都可以。

生产应用程序上出现错误。

我已经尝试制作所有东西 public，并且在同一个包中。此错误在版本 9 上仍然存在。

    new TestTask(this, "test", true).execute(value);

public class TestTask extends AsyncTask<String, Void, String> {

    private String param1;
    private boolean param2;
    private String number;
    private WeakReference<Context> appReference;

    TestTask(Context context, String param1, boolean param2) {
        this.appReference = new WeakReference<>(context);
        this.param1 = param1;
        this.param2 = param2;
    }

    @Override
    public String doInBackground(String... values) {
        try {
            number = values[0];

            if(param2)
                performVib();

            ResponseEvent response = new TestSnmp(param1).set(number);

        if( appReference.get()!=null && m_debugMode) {
            Toast.makeText(appReference.get(), "Response: " + response, Toast.LENGTH_SHORT).show();
        }


        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    public void onPostExecute(String result) {
        super.onPostExecute(result);
        try {
            if( appReference.get()!=null ) {
                Toast.makeText(appReference.get(), "Some text", Toast.LENGTH_SHORT).show();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

这是堆栈：

Answer 1

我将构造函数从 Bbox Send 更改为 TestTask，运行 Android 9 上的代码。它正在运行。

Answer 2

我发现问题来自 Proguard。

我在 proguard-rules.pro 中添加了这一行： -保持 class org.snmp4j.** {*;} 它现在似乎可以工作了！
