UpdateActivity
1.定义
private String versionName;
private int versionCode;
MyReceiver receiver = new MyReceiver();
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;
//服务器中APK下载地址
private String updateurl;
private Context context;
//自动更新的实现类
private UpdateServicelmpl UpdateService;
2.获得版本号
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//获得APP版本名称和版本号
versionName = DeviceInfoUtil.getAppVersionName(getApplicationContext());
versionCode = DeviceInfoUtil.getAppVersionCode(getApplicationContext());
// Log.i("测试：", "versionName:"+versionName+",versionCode:"+versionCode);
//更新接口
UpdateService = new UpdateServicelmpl(handler);
UpdateVO updatevo = new UpdateVO();
try {
UpdateService.UpdateClient(updatevo);
} catch (Exception e) {
e.printStackTrace();
}
regist();
}
3.处理返回消息
public final Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
Bundle bundle = msg.getData();
switch (msg.arg1) {
case UPDATA_CLIENT:
//处理服务器返回的结果
handleUpdateClientResult(bundle);
break;
}
}
};
4.处理接口返回结果
private void handleUpdateClientResult(Bundle bundle){
String json = bundle.getString(FunctionListEnum.UpdateClient.toString());
ObjectMapper objectMapper = new ObjectMapper();
if (null != json && !"".equals(json)){
try {
UpdateVO updatevo = objectMapper.readValue(json,UpdateVO.class);
if (null != updatevo){
int serverversioncode = updatevo.getServerVersionCode();
updateurl = updatevo.getUrl();
// if ( !"".equals(serverversioncode)){
if (versionCode <serverversioncode){
//对话框通知用户升级程序
showUpdataDialog();
}else
//进入程序主界面
LoginMain();
// }
}
} catch (IOException e) {
e.printStackTrace();
}
}else{
Toast.makeText(getApplicationContext(), "下载新版本失败", Toast.LENGTH_SHORT).show();
LoginMain();
}
}
5.弹出对话框提示更新
/**
* 弹出对话框通知用户更新程序
弹出对话框的步骤：
1.创建alertDialog的builder.
2.要给builder设置属性, 对话框的内容,样式,按钮
3.通过builder 创建一个对话框
4.对话框show()出来
*/
protected void showUpdataDialog() {
AlertDialog.Builder builer = new AlertDialog.Builder(this);
builer.setTitle("是否进行版本升级？");
// builer.setMessage(info.getDescription());.
//当点确定按钮时从服务器上下载 新的apk 然后安装
builer.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Log.i("提示","下载apk,更新");
dialog.dismiss();
downLoadApk();
}
});
//当点取消按钮时进行登录
builer.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
LoginMain();
}
});
AlertDialog dialog = builer.create();
dialog.show();
}
6.从服务器中下载APK
/**
* 从服务器中下载APK
*/
private void downLoadApk(){
if (TextUtils.isEmpty(updateurl)) {
return;
}
try {
String serviceString = Context.DOWNLOAD_SERVICE;
context = this.getApplicationContext();
final DownloadManager downloadManager = (DownloadManager) context.getSystemService(serviceString);
//将下载地址url放入uri中
// //从资源文件获取服务器 地址
// String path = getResources().getString(R.string.serverurl);
Uri uri = Uri.parse(updateurl);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.allowScanningByMediaScanner();
request.setVisibleInDownloadsUi(true);
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setMimeType("application/vnd.android.package-archive");
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/app-debug/","app-debug.apk");
if (file.exists()){
file.delete();
}
request.setDestinationInExternalPublicDir(Environment.getExternalStorageDirectory().getAbsolutePath()+"/app-debug/", "app-debug.apk");
// File newfile = new File(String.valueOf(request));
//获得唯一下载id
long refernece = downloadManager.enqueue(request);
//将id放进Intent
Intent localIntent = new Intent(BROADCAST_ACTION);
localIntent.putExtra(EXTENDED_DATA_STATUS,refernece);
//查询下载信息
DownloadManager.Query query=new DownloadManager.Query();
query.setFilterById(refernece);
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){
case DownloadManager.STATUS_RUNNING:
Toast.makeText(getApplicationContext(), "下载中", Toast.LENGTH_SHORT).show();
break;
//如果下载状态为成功
case DownloadManager.STATUS_SUCCESSFUL:
isGoging=false;
installApkDialog();
//退出当前程序
// android.os.Process.killProcess(android.os.Process.myPid());
// InstallAPK();
// //调用LocalBroadcastManager.sendBroadcast将intent传递回去
// mLocalBroadcastManager = LocalBroadcastManager.getInstance(this);
// mLocalBroadcastManager.sendBroadcast(localIntent);
break;
case DownloadManager.STATUS_FAILED:
isGoging = false;
Toast.makeText(getApplicationContext(), "下载新版本失败", Toast.LENGTH_SHORT).show();
LoginMain();
break;
case DownloadManager.STATUS_PAUSED:
searchReason();
break;
}
}
if(cursor!=null){
cursor.close();
}
}
}catch(Exception e){
e.printStackTrace();
}
} catch (Exception exception) {
Toast.makeText(getApplicationContext(), "下载新版本失败", Toast.LENGTH_SHORT).show();
LoginMain();
}
}
7.安装新版本（未修改好，自动安装提示解析错误，手动安装成功）
protected void installApkDialog(){
AlertDialog.Builder builer = new AlertDialog.Builder(this);
builer.setTitle("退出安装新版本");
// builer.setMessage(info.getDescription());.
//当点确定按钮时从服务器上下载 新的apk 然后安装
builer.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
android.os.Process.killProcess(android.os.Process.myPid());
}
});
//当点取消按钮时进行登录
// builer.setNegativeButton("否", new DialogInterface.OnClickListener() {
// public void onClick(DialogInterface dialog, int which) {
// // TODO Auto-generated method stub
// //退出当前程序
// android.os.Process.killProcess(android.os.Process.myPid());
// }
// });
AlertDialog dialog = builer.create();
dialog.show();
}
8.下载暂停原因分析
//下载暂停原因
private void searchReason(){
String serviceString = Context.DOWNLOAD_SERVICE;
DownloadManager downloadManager;
downloadManager = (DownloadManager)getSystemService(serviceString);
// 为暂停的下载任务创建query
DownloadManager.Query pausedDownloadQuery = new DownloadManager.Query();
pausedDownloadQuery.setFilterByStatus(DownloadManager.STATUS_PAUSED);
// Query the Download Manager for paused downloads.
Cursor pausedDownloads = downloadManager.query(pausedDownloadQuery);
// Find the column indexes for the data we require.
int reasonIdx = pausedDownloads.getColumnIndex(DownloadManager.COLUMN_REASON);
while (pausedDownloads.moveToNext()) {
int reason = pausedDownloads.getInt(reasonIdx);
switch (reason) {
case DownloadManager.PAUSED_QUEUED_FOR_WIFI :
pausedDownloads.close();
showNoWifiDialog();
break;
case DownloadManager.PAUSED_WAITING_FOR_NETWORK :
pausedDownloads.close();
showNoNetworkDialog();
break;
case DownloadManager.PAUSED_WAITING_TO_RETRY :
// Close the result Cursor.
pausedDownloads.close();
showRetryDialog();
break;
case DownloadManager.PAUSED_UNKNOWN:
// Close the result Cursor.
pausedDownloads.close();
showRetryDialog();
break;
}
}
}
//显示由于移动网络数据问题，等待WiFi连接能用后再重新进入下载队列。
protected void showNoWifiDialog() {
AlertDialog.Builder builer = new AlertDialog.Builder(this);
builer.setTitle("移动网络数据有问题，需要等待wifi连接后才能下载");
// builer.setMessage(info.getDescription());.
//当点确定按钮时从服务器上下载 新的apk 然后安装
builer.setPositiveButton("重新下载", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Log.i("提示","下载apk,更新");
downLoadApk();
}
});
//当点取消按钮时进行登录
builer.setNegativeButton("取消下载", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
LoginMain();
}
});
AlertDialog dialog = builer.create();
dialog.show();
}
//可能由于没有网络连接而无法下载，等待有可用的网络连接恢复。.
protected void showNoNetworkDialog() {
AlertDialog.Builder builer = new AlertDialog.Builder(this);
builer.setTitle("没有网络连接");
// builer.setMessage(info.getDescription());.
//当点确定按钮时从服务器上下载 新的apk 然后安装
builer.setPositiveButton("重试", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Log.i("提示","下载apk,更新");
downLoadApk();
}
});
//当点取消按钮时进行登录
builer.setNegativeButton("取消下载", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
LoginMain();
}
});
AlertDialog dialog = builer.create();
dialog.show();
}
//由于重重原因导致下载暂停，等待重试。
protected void showRetryDialog(){
AlertDialog.Builder builer = new AlertDialog.Builder(this);
builer.setTitle("由于未知原因导致下载暂停，是否等待重试");
// builer.setMessage(info.getDescription());.
//当点确定按钮时从服务器上下载 新的apk 然后安装
builer.setPositiveButton("重试", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Log.i("提示","下载apk,更新");
downLoadApk();
}
});
//当点取消按钮时进行登录
builer.setNegativeButton("取消下载", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
LoginMain();
}
});
AlertDialog dialog = builer.create();
dialog.show();
}
9.注册广播（未用到）
//注册广播
private void regist() {
IntentFilter intentFilter = new IntentFilter(UpdateActivity.BROADCAST_ACTION);
intentFilter.addCategory(Intent.CATEGORY_DEFAULT);
LocalBroadcastManager.getInstance(this).registerReceiver(receiver, intentFilter);
}
//接受到广播，处理传递过来的数据，下载完成，自动安装应用
private class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String data = intent.getStringExtra(UpdateActivity.EXTENDED_DATA_STATUS);
Log.i("test", data);
try {
if(null!= data && !"".equals(data)){
long id = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
Toast.makeText(UpdateActivity.this, "编号："+id+"的下载任务已经完成！", Toast.LENGTH_SHORT).show();
intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/app-debug.apk")),
"application/vnd.android.package-archive");
startActivity(intent);
}else{
Toast.makeText(getApplicationContext(), "下载新版本失败", Toast.LENGTH_SHORT).show();
showRetryDialog();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
//取消注册广播
protected void onDestroy() {
super.onDestroy();
// cancel();
LocalBroadcastManager.getInstance(this).unregisterReceiver(receiver);
}
10.安装新版本
private void InstallAPK() {
Intent intent = new Intent();
//执行动作
intent.setAction(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//执行的数据类型
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/app-debug.apk")),
"application/vnd.android.package-archive");
startActivity(intent);
}
11.进入主界面
/*
* 进入程序的主界面
*/
private void LoginMain(){
Intent intent = new Intent(this,ActivateBoxActivity.class);
startActivity(intent);
//结束掉当前的activity
this.finish();
}
