Web からコンテンツをダウンロードするアプリがあります。音楽、ビデオ、PDF.... ダウンロード マネージャーのようなものです。
しかし、今ではコンテンツをダウンロードするたびにクラッシュしています:

私はすでにこれをマニフェストに追加しました:
<application
android:name=".app.MyApp"
android:allowBackup="true"
android:hardwareAccelerated="true"
android:icon="@mipmap/ic_launcher"
tools:replace="android:icon"
android:label="@string/app_name"

コードサンプル:
private OkHttpClient client;
onViewCreated...{
//Initiate OkHttp with interceptor
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
client = new OkHttpClient.Builder()
.addInterceptor(logging)
.build();
...
}
private void downloadPdf() {
AsyncTask.execute(new Runnable() {
@Override
public void run() {
client
.newCall(getRequest(Config._API_PDF))
.enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
...
}
@Override
public void onResponse(Call call, Response response) throws IOException {
try {
InputStream ins = response.body().byteStream();
BufferedReader in = new BufferedReader(new InputStreamReader(ins));
String lineTotal = "";
while (true) {
String line = in.readLine();
if (line == null)
break;
else
lineTotal += line;
}
...json parsing ...
