安卓APP升级
APP升级的流程是
1 访问服务器获取APP更新消息
2 下载APP到本地
3 从本地更新到本地
1 从服务器获取APP消息
一般是用HTTP来获取 ,主要目的是为了获取是否有更新包, 更新包下载路径
private boolean check_server_version()
{
AsyncHttpClient client = new AsyncHttpClient();
RequestParams params = new RequestParams();
path =mserverIP + path ;
Log.e("data_____",path);
params.put("serial_num","hello");
client.post(path, params, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, cz.msebera.android.httpclient.Header[] headers, byte[] responseBody) {
String s = new String(responseBody);
JSONObject jsonObject1 = null;
try {
jsonObject1 = new JSONObject(s );
Log.e("data_",jsonObject1.toString());
if(jsonObject1.getInt("apk_state")==1){
is_update = true;
update_msg = jsonObject1.getString("apk_msg");
version = jsonObject1.getDouble("apk_version");
String apk_name = jsonObject1.getString("apk_name");
String apk_dir=jsonObject1.getString("apk_dir");
mdownload_path = mserverIP+ "/tractor_client/download_apk/" + apk_name;
Log.e("data_",mdownload_path);
showUpdataDialog("新版本:"+version+"\r\n"+update_msg);
}else{
is_update = false;
}
}catch (Exception e){
// Toast.makeText(context,"注册失败!",Toast.LENGTH_SHORT).show();
}
}
@Override
public void onFailure(int statusCode, cz.msebera.android.httpclient.Header[] headers, byte[] responseBody, Throwable error) {
}
});
return true;
}2 下载APP
mdownload_path是服务器APP路径
downLoadPath是安卓本地路径,这里记得加SD卡路径
private void downloadApk() {
try {
final long startTime = System.currentTimeMillis();
Log.i("DOWNLOAD", "startTime=" + startTime);
//获取文件名
URL myURL = new URL(mdownload_path);
URLConnection conn = myURL.openConnection();
conn.connect();
InputStream is = conn.getInputStream();
int fileSize = conn.getContentLength();//根据响应获取文件大小
Log.i("DOWNLOAD", "总大小="+fileSize);
if (fileSize <= 0) throw new RuntimeException("无法获知文件大小 ");
if (is == null) throw new RuntimeException("stream is null");
File file1 = new File(downLoadPath);
if (!file1.exists()) {
file1.mkdirs();
}
//把数据存入路径+文件名
FileOutputStream fos = new FileOutputStream(downLoadPath + "/" + newApkName);
byte buf[] = new byte[1024];
int downLoadFileSize = 0;
do {
//循环读取
int numread = is.read(buf);
if (numread == -1) {
break;
}
fos.write(buf, 0, numread);
downLoadFileSize += numread;
Log.i("DOWNLOAD", "downLoadFileSize="+downLoadFileSize);
Log.i("DOWNLOAD", "fileSize="+fileSize);
Log.i("DOWNLOAD", "download downLoadFileSize="+(int)((float)downLoadFileSize*100/fileSize));
progressDialog.setProgress((int)((float)downLoadFileSize*100/fileSize));
//更新进度条
} while (true);
delOldApk();
progressDialog.dismiss();
showInstallDialog("下载完成，是否安装？");
Log.i("DOWNLOAD", "download success");
Log.i("DOWNLOAD", "totalTime=" + (System.currentTimeMillis() - startTime));
is.close();
} catch (Exception ex) {
Log.e("DOWNLOAD", "111111 error: " + ex.getMessage(), ex);
progressDialog.cancel();
try{
AlertDialog.Builder adBd=new AlertDialog.Builder(context);
adBd.setTitle("下载错误");
adBd.setMessage("检查网络或者服务器!");
adBd.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
adBd.show();
}
catch (Exception e){
Log.e("DOWNLOAD_EEE", "111111 error: " + ex.getMessage(), ex);
}
}
}3 更新APP
这里直接把安装包的路径传递过来,然后调用系统的安装器进行安装
private void installApk(Context context, File file) {
Intent intent = new Intent(Intent.ACTION_VIEW);
//判断是否是AndroidN以及更高的版本
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Uri contentUri = FileProvider.getUriForFile(context, "com.baozun.book.fileProvider", file);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setDataAndType(contentUri, "application/vnd.android.package-archive");
} else {
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
}
context.startActivity(intent);
}
