APK版本更新，软件下载更新，通知栏显示进度
首先你要添加权限
<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
然后 只要启动一个服务就可以实现软件下载更新，通知栏显示进度
package com.example.updateservice; import android.app.Activity; import android.app.AlertDialog; import android.app.AlertDialog.Builder; import android.app.Dialog; import android.content.Context; import android.content.DialogInterface; import android.content.Intent; import android.os.Bundle; public class MainActivity extends Activity { Context mContext; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mContext = this; showDialog(); } private void showDialog(){ AlertDialog.Builder builder = new Builder(mContext); builder.setTitle("升级提示"); builder.setMessage("版本：1.0.1\n大小：6.5M\n1、修改Bug\n2、增加功能"); builder.setNegativeButton("稍后再说", new AlertDialog.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }); builder.setPositiveButton("马上跟新", new AlertDialog.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); Intent intent = new Intent(mContext,DownloadService.class); intent.putExtra("url", "http://surveyapp.fy.chaoxing.com/app/LauncherDemo5.apk"); startService(intent); } }); builder.show(); } }
