Android 更新模块 自定义Update
写这个总结是因为在项目中碰到了Android系统兼容的BUG
Android项目原本使用的是API提供的下载方法
如下:
DownloadManager downloadManager = (DownloadManager) getSystemService(Activity.DOWNLOAD_SERVICE);DownloadManager.Request request = new Request(Uri.parse(dl));request.setTitle(getString(R.string.app_name));request.setDestinationUri(getDownloadName(getIntent().getStringExtra("version_name")));long reference = downloadManager.enqueue(request);UserSettingHelper.getInstance().setUpgradeKey(reference);
但如三星 华为 等手机它自带的系统中 删除掉了google服务从而导致崩溃
在网上找了资料 然后改吧改吧总算快速修复了bug:
1) 主activity
package com.example.updataapk;import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;/** * * @author baozi * */public class MainActivity extends Activity {// 地址private String dl = "http://17shihui.cn/download/shihui.apk";@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Function_Utility.setAppContext(getApplicationContext());findViewById(R.id.button1).setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {Uri uri = Uri.parse(dl);Intent intent = new Intent(Intent.ACTION_VIEW, uri);startActivity(intent);}});findViewById(R.id.button2).setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {try {download(dl);} catch (Exception e) {e.printStackTrace();}}});}private void download(String dl) throws Exception {if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.GINGERBREAD) {Intent service = new Intent(this, DownloadService.class);service.putExtra(DownloadService.INTENT_URL, dl);startService(service);} else {Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(dl));startActivity(intent);}}}

3) 下载到手机的地址
package com.example.updataapk;import java.io.File;import java.io.IOException;import android.annotation.SuppressLint;import android.content.Context;import android.os.Environment;@SuppressWarnings("deprecation")@SuppressLint({ "DefaultLocale", "SimpleDateFormat" })public class Function_Utility {private static Context mAppContext;public static void setAppContext(Context context) {mAppContext = context;}public static Context getAppContext() {return mAppContext;}/** * 下载到SD卡地址 */public static String getUpgradePath() {String filePath = getAppRootPath() + "/upgrade/";File file = new File(filePath);if (!file.isDirectory()) {file.mkdirs();}file = null;return filePath;}public static String getAppRootPath() {String filePath = "/weimicommunity";if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {filePath = Environment.getExternalStorageDirectory() + filePath;} else {filePath = getAppContext().getCacheDir() + filePath;}File file = new File(filePath);if (!file.exists()) {file.mkdirs();}file = null;File nomedia = new File(filePath + "/.nomedia");if (!nomedia.exists())try {nomedia.createNewFile();} catch (IOException e) {e.printStackTrace();}return filePath;}}
4) Androidmanifest.xml
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.updataapk" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" /> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.example.updataapk.MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <service android:name="com.example.updataapk.DownloadService" > </service> </application></manifest>
