我有一个应用程序可以从网络上下载内容。 音乐、视频、pdf……就像一个下载管理器。
但现在每次下载内容时都会崩溃:

我已经将它添加到我的 list 中:
<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"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme.NoActionBar">
代码示例:
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 ...
...
我的 BuildGradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.my.app"
minSdkVersion 17
targetSdkVersion 22
versionCode 1
versionName "1.0"
ndk { abiFilters "armeabi", "x86", "mips" }
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
final SUPPORT_LIBRARY_VERSION = '23.2.0'
final PLAY_SERVICES_VERSION = '8.3.0'
final RETROFIT_VERSION = '2.0.0'

compile "com.android.support:design:$SUPPORT_LIBRARY_VERSION"
compile "com.android.support:support-v4:$SUPPORT_LIBRARY_VERSION"

compile 'com.google.code.gson:gson:2.6.2'
compile 'com.jakewharton:butterknife:7.0.1'
}
然后我有另一种类似的方法来下载视频...
有没有人以前遇到过这个？ 谢谢
最佳答案
当您使用 HttpLoggingInterceptor.Level.BODY 时，您尝试下载大文件，会将所有主体保存在内存中以供日志使用。
这很容易导致 OOM。
尝试删除日志正文或只记录 NONE 、基本或标题，然后重试。
当您尝试获取大文件时，可以像这样在 retrofit2 中使用 @Streaming。
@Streaming
@GET
fun downloadFileWithDynamicUrlSync(@Url fileUrl: String): Call<ResponseBody>
尝试在此处删除日志主体。
onViewCreated...{
//Initiate OkHttp with interceptor
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
试试这个。
onViewCreated...{
//Initiate OkHttp with interceptor
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.NONE);
关于java - 致命异常 : java. lang.OutOfMemoryError 使用 okhttp3 okio 下载文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36643280/
