我正在运行一个应用来测试我是否可以在运行Android API 19的手机上使用Microsoft Translator API。但是，当我按下按钮获取翻译文本时，而不是将文本“This is my dog”翻译成法语，Microsoft Translator API返回“”。

我的代码是：
public class MainActivity extends AppCompatActivity {
TextView subject;
Button submit;
TextView result;
String stayalive;
String translatedText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
subject = (TextView) findViewById(R.id.textView);
submit = (Button) findViewById(R.id.button);
result = (TextView) findViewById(R.id.textView2);
Translate.setClientId("CLIENT ID");
Translate.setClientSecret("CLIENT SECRET");
submit.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
class MyAsyncTask extends AsyncTask<DownloadManager.Request, Void, String> {
protected String doInBackground() {
try {
translatedText = Translate.execute("This is my dog", Language.AUTO_DETECT, Language.FRENCH);
return "";
} catch (Exception e) {
e.printStackTrace();
return "";
// I can't do a void
}
}
@Override
protected String doInBackground(DownloadManager.Request... params) {
return null;
}
@Override
protected void onPostExecute(String s) {
if (subject != null){
subject.setText(translatedText);
Context context = getApplicationContext();
CharSequence text = translatedText;
// the Toast didn't have any text in it
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
} else {
Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}
}
}
new MyAsyncTask().execute();
}
});
}
}
的AndroidManifest.xml：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.inspiron.translat">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<uses-permission android:name="android.permission.INTERNET"/>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
错误是因为我的代码还是因为Microsoft Translator API本身？ （我正在使用来自https://code.google.com/archive/p/microsoft-translator-java-api/downloads的microsoft-translator-java-api-0.6.2-jar-with-dependencies.jar。）
更新2 ：我从Permission denied (missing INTERNET permission?): But permission is given得到了答案。显然我应该将<uses-permission>标签放在application之上。
答案 0 :(得分：0)
为什么你需要两个doInBackground调用？删除一个并尝试
