IllegalAccessError仅在AsyncTask函数执行期间在Android 9上发生

在Android 9上有什么事情要做吗？其他所有版本都可以。

在生产应用程序上看到错误。

我已经尝试将所有内容公开化，并使用同一包。版本9上仍然存在此错误。

    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

我将构造器从BboxSend更改为TestTask，并在Android 9上运行了代码。

Answer 2

我发现问题出在Proguard。

我在proguard-rules.pro中添加了这一行： -keep org.snmp4j类。** {*;} 看来现在可以了！

IllegalAccessError仅在AsyncTask内的Android 9上
