- 错误原因：
Android 4.4及以下的系统默认不支持TLS协议，所以遇到使用TLS协议的网站就无法访问了。
解决方法如下：
首先需要添加一个Glide对 OkHttp 集成库的依赖:
compile "com.github.bumptech.glide:okhttp3-integration:4.11.0"
依赖参考：https://muyangmin.github.io/glide-docs-cn/int/okhttp3.html
1、创建一个SSLSocketFactoryCompat.java文件，内容如下：
import android.os.Build;
import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.GeneralSecurityException;
import java.util.Arrays;
import java.util.HashSet;
import java.util.LinkedList;
import java.util.List;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.X509TrustManager;
/**
* Android 4.4及以下的系统默认不支持TLS协议
*/
public class SSLSocketFactoryCompat extends SSLSocketFactory {
private SSLSocketFactory defaultFactory;
// Android 5.0+ (API level21) provides reasonable default settings
// but it still allows SSLv3
// https://developer.android.com/about/versions/android-5.0-changes.html#ssl
static String protocols[] = null, cipherSuites[] = null;
static {
try {
SSLSocket socket = (SSLSocket) SSLSocketFactory.getDefault().createSocket();
if (socket != null) {
/* set reasonable protocol versions */
// - enable all supported protocols (enables TLSv1.1 and TLSv1.2 on Android <5.0)
// - remove all SSL versions (especially SSLv3) because they're insecure now
List<String> protocols = new LinkedList<>();
for (String protocol : socket.getSupportedProtocols())
if (!protocol.toUpperCase().contains("SSL"))
protocols.add(protocol);
SSLSocketFactoryCompat.protocols = protocols.toArray(new String[protocols.size()]);
/* set up reasonable cipher suites */
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
// choose known secure cipher suites
List<String> allowedCiphers = Arrays.asList(
// TLS 1.2
"TLS_RSA_WITH_AES_256_GCM_SHA384",
"TLS_RSA_WITH_AES_128_GCM_SHA256",
"TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256",
"TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256",
"TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384",
"TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256",
"TLS_ECHDE_RSA_WITH_AES_128_GCM_SHA256",
// maximum interoperability
"TLS_RSA_WITH_3DES_EDE_CBC_SHA",
"TLS_RSA_WITH_AES_128_CBC_SHA",
// additionally
"TLS_RSA_WITH_AES_256_CBC_SHA",
"TLS_ECDHE_ECDSA_WITH_3DES_EDE_CBC_SHA",
"TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA",
"TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA",
"TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA");
List<String> availableCiphers = Arrays.asList(socket.getSupportedCipherSuites());
// take all allowed ciphers that are available and put them into preferredCiphers
HashSet<String> preferredCiphers = new HashSet<>(allowedCiphers);
preferredCiphers.retainAll(availableCiphers);
/* For maximum security, preferredCiphers should *replace* enabled ciphers (thus disabling
* ciphers which are enabled by default, but have become unsecure), but I guess for
* the security level of DAVdroid and maximum compatibility, disabling of insecure
* ciphers should be a server-side task */
// add preferred ciphers to enabled ciphers
HashSet<String> enabledCiphers = preferredCiphers;
enabledCiphers.addAll(new HashSet<>(Arrays.asList(socket.getEnabledCipherSuites())));
SSLSocketFactoryCompat.cipherSuites = enabledCiphers.toArray(new String[enabledCiphers.size()]);
}
}
} catch (IOException e) {
throw new RuntimeException(e);
}
}
public SSLSocketFactoryCompat(X509TrustManager tm) {
try {
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, (tm != null) ? new X509TrustManager[]{tm} : null, null);
defaultFactory = sslContext.getSocketFactory();
} catch (GeneralSecurityException e) {
throw new AssertionError(); // The system has no TLS. Just give up.
}
}
private void upgradeTLS(SSLSocket ssl) {
// Android 5.0+ (API level21) provides reasonable default settings
// but it still allows SSLv3
// https://developer.android.com/about/versions/android-5.0-changes.html#ssl
if (protocols != null) {
ssl.setEnabledProtocols(protocols);
}
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP && cipherSuites != null) {
ssl.setEnabledCipherSuites(cipherSuites);
}
}
@Override
public String[] getDefaultCipherSuites() {
return cipherSuites;
}
@Override
public String[] getSupportedCipherSuites() {
return cipherSuites;
}
@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
Socket ssl = defaultFactory.createSocket(s, host, port, autoClose);
if (ssl instanceof SSLSocket)
upgradeTLS((SSLSocket) ssl);
return ssl;
}
@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
Socket ssl = defaultFactory.createSocket(host, port);
if (ssl instanceof SSLSocket)
upgradeTLS((SSLSocket) ssl);
return ssl;
}
@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
Socket ssl = defaultFactory.createSocket(host, port, localHost, localPort);
if (ssl instanceof SSLSocket)
upgradeTLS((SSLSocket) ssl);
return ssl;
}
@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
Socket ssl = defaultFactory.createSocket(host, port);
if (ssl instanceof SSLSocket)
upgradeTLS((SSLSocket) ssl);
return ssl;
}
@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
Socket ssl = defaultFactory.createSocket(address, port, localAddress, localPort);
if (ssl instanceof SSLSocket)
upgradeTLS((SSLSocket) ssl);
return ssl;
}
}
2、在创建OkHttpClient的时候，添加这个SSLSocketFactory（用单例模式来每次获取同一个全局的OkHttpClient）：
import java.security.cert.CertificateException;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.X509TrustManager;
import okhttp3.OkHttpClient;
/**
* 自定义okHttpClient
*/
public class SSLOkHttpClient {
private static OkHttpClient okHttpClient;
public synchronized static OkHttpClient getClient() {
if (okHttpClient == null) {
OkHttpClient.Builder builder = new OkHttpClient.Builder();
try {
// 自定义一个信任所有证书的TrustManager，添加SSLSocketFactory的时候要用到
final X509TrustManager trustAllCert =
new X509TrustManager() {
@Override
public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
}
@Override
public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
}
@Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[]{};
}
};
final SSLSocketFactory sslSocketFactory = new SSLSocketFactoryCompat(trustAllCert);
builder.sslSocketFactory(sslSocketFactory, trustAllCert);
} catch (Exception e) {
throw new RuntimeException(e);
}
okHttpClient = builder.build();
}
return okHttpClient;
}
}
3、新建OkHttpAppGlideModule，替换Glide 使用的OKhttp(我用的是Glide4.x 以上版本的，参考Glide用法)
import android.content.Context;
import androidx.annotation.NonNull;
import com.bumptech.glide.Glide;
import com.bumptech.glide.Registry;
import com.bumptech.glide.annotation.GlideModule;
import com.bumptech.glide.integration.okhttp3.OkHttpUrlLoader;
import com.bumptech.glide.load.model.GlideUrl;
import com.bumptech.glide.module.AppGlideModule;
import org.jetbrains.annotations.NotNull;
import java.io.InputStream;
import okhttp3.OkHttpClient;
/**
* grade 4.x 在Android4.4手机上的适配
* Android 4.4及以下的系统默认不支持TLS协议
*/
@GlideModule
public class OkHttpAppGlideModule extends AppGlideModule {
@Override
public boolean isManifestParsingEnabled() {
return false;
}
@Override
public void registerComponents(@NonNull @NotNull Context context, @NonNull @NotNull Glide glide, @NonNull @NotNull Registry registry) {
OkHttpClient client = SSLOkHttpClient.getClient();
registry.replace(GlideUrl.class, InputStream.class,
new OkHttpUrlLoader.Factory(client));
}
}
