第一步添加如下代碼
<service
android:name=".AppUpdate.DownloadService"
android:exported="false">
<intent-filter>
<action android:name="com.example.android.threadsample.BROADCAST" />
</intent-filter>
</service>
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="cc.booku.owlbox.FileProvider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
第二步。新建文件夾AppUpdate，並在下面新建如下文件AppUpdate文件我沒用到，就不貼代碼了
代碼：
package cc.booku.owlbox.AppUpdate;
/**
* Created by yangwenlong on 2019/10/7.
*/
public class app_version_class {
private String title,content,time,down_url,version;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public String getTime() {
return time;
}
public void setTime(String time) {
this.time = time;
}
public String getDown_url() {
return down_url;
}
public void setDown_url(String down_url) {
this.down_url = down_url;
}
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
}
package cc.booku.owlbox.AppUpdate;
import android.app.DownloadManager;
import android.app.IntentService;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Environment;
import android.support.annotation.Nullable;
import android.support.v4.content.LocalBroadcastManager;
import android.util.Log;
import java.io.File;
public class DownloadService extends IntentService {
private static final String TAG = "DownloadService";
public static final String BROADCAST_ACTION = "com.example.android.threadsample.BROADCAST";
public static final String EXTENDED_DATA_STATUS = "com.example.android.threadsample.STATUS";
private LocalBroadcastManager mLocalBroadcastManager;
public DownloadService() {
super("DownloadService");
}
@Override
protected void onHandleIntent(@Nullable Intent intent) {
//獲取下載地址
String url = intent.getDataString();
Log.i(TAG, url);
//獲取DownloadManager對象
DownloadManager downloadManager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
//指定APK緩存路徑和應用名稱,比如我這個路徑就是/storage/emulated/0/Download/vooloc.apk
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "app-release.apk");
//設置網絡下載環境爲wifi或者移動數據
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
//設置顯示通知欄，下載完成後通知欄自動消失
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE);
//設置通知欄標題
request.setTitle("貓頭鷹下載更新");
//設置這個下載的描述，顯示在通知中
request.setDescription("未彈出安裝界面，請到系統下載，手動安裝");
//設置類型爲.apk
request.setMimeType("application/vnd.android.package-archive");
//獲得唯一下載id
long requestId = downloadManager.enqueue(request);
//將id放進Intent
Intent localIntent = new Intent(BROADCAST_ACTION);
localIntent.putExtra(EXTENDED_DATA_STATUS, requestId);
//查詢下載信息
DownloadManager.Query query = new DownloadManager.Query();
//只包括帶有給定id的下載。
query.setFilterById(requestId);
try {
boolean isGoging = true;
while (isGoging) {
Cursor cursor = downloadManager.query(query);
if (cursor != null && cursor.moveToFirst()) {
int status = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_STATUS));
switch (status) {
//如果下載狀態爲成功
case DownloadManager.STATUS_SUCCESSFUL:
isGoging = false;
//調用LocalBroadcastManager.sendBroadcast將intent傳遞回去
mLocalBroadcastManager = LocalBroadcastManager.getInstance(this);
mLocalBroadcastManager.sendBroadcast(localIntent);
// String fileName = "app-release.apk";
// Intent i = new Intent();
// i.setAction(Intent.ACTION_VIEW);
// i.setDataAndType(Uri.fromFile(new File(fileName) ), "application/vnd.android.package-archive");
// startActivity(i);
break;
}
}
if (cursor != null) {
cursor.close();
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
然後是activity裏面的代碼：
/********************************程序更新******************************
