.build();
client.newCall(request).enqueue(new Callback() {

}

int len;
try {

//下载中,更新下载进度

}

//4.下载完成,安装apk

} catch (Exception e) {

} finally {

//断点续传

if (file.exists())
file.delete();
try {
file.createNewFile();
return file;
} catch (IOException e) {
e.printStackTrace();
}
return null ;
}
三、安装apk
3.1项目的src/res新建个xml文件夹再自定义一个file_paths文件
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path name="name1" path="test1" />
</paths>
3.2在清单文件中配置
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.mydomain.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
3.3安装apk
//安装apk,包含7.0
public void installApk(Context context, File file) {
if (context == null) {
return;
}
String authority = getApplicationContext().getPackageName() + ".fileProvider";
Uri apkUri = FileProvider.getUriForFile(context, authority, file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//判读版本是否在7.0以上
if (Build.VERSION.SDK_INT >= 24) {
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setDataAndType(apkUri, "application/vnd.android.package-archive");
} else {
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
}
context.startActivity(intent);
//弹出安装窗口把原程序关闭。
//避免安装完毕点击打开时没反应
Process.killProcess(android.os.Process.myPid());
}
四、取消订阅
@Override
protected void onDestroy() {
super.onDestroy();
downDisposable.dispose();//取消订阅
}
五、自定义Dialog
