Android 检查更新、下载、安装功能的实现
android检查更新、下载、安装
前言:
由于友盟更新即将下线,我们就修改了更新逻辑,自己检查更新、下载、安装,但是检查更新还是要依赖于友盟中的在线参数:
1.MainActivity.Java:
public class MainActivity extends BaseActivity{ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); CheckUpdateUtil.checkUpdate(this);//检查更新 } }
2.CheckUpdateUtil.java:
package com.monkey.monkeymushroom.util; import android.app.AlertDialog; import android.app.NotificationManager; import android.content.Context; import android.content.Intent; import android.net.Uri; import android.os.Environment; import android.support.v4.app.NotificationCompat; import android.text.TextUtils; import android.view.Gravity; import android.view.View; import android.view.Window; import android.view.WindowManager; import android.widget.Button; import android.widget.TextView; import android.widget.Toast; import com.lidroid.xutils.HttpUtils; import com.lidroid.xutils.exception.HttpException; import com.lidroid.xutils.http.ResponseInfo; import com.lidroid.xutils.http.callback.RequestCallBack; import com.umeng.analytics.MobclickAgent; import java.io.File; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Date; /** * 检查更新工具类 */ public class CheckUpdateUtil { private static NotificationCompat.Builder builder; private static NotificationManager manager; private static final int UPDATE_ID = "0"; /** * 检查更新 * * @param context * @return */ public static boolean checkUpdate(Context context) { // 获取友盟在线参数(要更新的版本号) String force_version = MobclickAgent.getConfigParams(context, "version"); if (StringUtils.isEmpty(version)) { version = "1.0"; } // 版本号转换为数组 String[] mUpdateVersionArray = version.split(","); String curr_version_name = SysInfoUtils.getVersionName(context); for (int i = 0; i < mUpdateVersionArray .length; i++) {//循环获取在线参数上设置的版本号 if (curr_version_name.equals(mUpdateVersionArray [i])) {//如果有,代表要更新 if ((mUpdateVersionArray .length > i + 1) && ("Y".equals(mUpdateVersionArray [i + 1]))) {//判断是否强更 showUpdateDialog(true, context); } else {//不强更 showUpdateDialog(false, context); } return true;// 只要找到对应的版本号,即有更新,结束循环 } } return false;//无更新 } /** * 显示更新对话框 * * @param isForceUpdate 是否强制更新 */ public static void showUpdateDialog(final boolean isForceUpdate, final Context context) { // 获取更新日志 String update_log = MobclickAgent.getConfigParams(context, "update_log"); // 最新版本 String new_version = MobclickAgent.getConfigParams(context, "new_version"); // 获取下载地址 final String download_path = MobclickAgent.getConfigParams(context, "new_version_path"); if (TextUtils.isEmpty(update_log) || TextUtils.isEmpty(download_path) || TextUtils.isEmpty(new_version)) { return; } LogMessage.e("monkey", "更新日志--> " + update_log + " 最新版本--> " + new_version + " 下载地址--> " + download_path); //弹框提示 final AlertDialog mAlertDialog = new AlertDialog.Builder(context).create(); mAlertDialog.show(); mAlertDialog.setCancelable(false); Window window = mAlertDialog.getWindow(); window.setGravity(Gravity.BOTTOM); window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT); View view = View.inflate(context, R.layout.dialog_update, null); window.setContentView(view); TextView log_head = (TextView) view.findViewById(R.id.log_head); TextView msg_tv = (TextView) view.findViewById(R.id.msg_tv); log_head.setText("v" + new_version + "更新日志:"); msg_tv.setText(update_log); Button update = (Button) view.findViewById(R.id.yes_btn); Button notNow = (Button) view.findViewById(R.id.no_btn); update.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { download(context, download_path); mAlertDialog.dismiss(); } }); notNow.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { mAlertDialog.dismiss(); } }); if (isForceUpdate) {//如果是强制更新,则不显示“以后再说”按钮 notNow.setVisibility(View.GONE); } } /** * 下载apk */ private static void download(final Context context, String download_path) { if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) { String apkName = download_path.substring(download_path.lastIndexOf("/") + 1); String target = Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + apkName; LogMessage.e("monkey", "apk target -->" + target); if (NetUtils.isNetConnect(context)) { HttpUtils httpUtils = new HttpUtils(1000 * 10);//为了方便使用了xUtils httpUtils.download(download_path, target, false, true, new RequestCallBack<File>() { @Override public void onStart() { super.onStart(); ToastUtil.show(context, "正在下载……"); //创建通知栏下载提示 builder = new NotificationCompat.Builder(context); builder.setSmallIcon(R.drawable.ic_launcher) .setOngoing(true) .setContentTitle("猴菇先生"); manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); } @Override public void onLoading(long total, long current, boolean isUploading) { super.onLoading(total, current, isUploading); LogMessage.e("monkey", "--> total " + total + " current " + current); int cur = (int) (current * 100 / total); LogMessage.e("monkey", "cur--> " + cur + "%"); builder.setProgress(100, cur, false)//更新进度 .setContentText(cur + "%"); manager.notify(UPDATE_ID, builder.build()); } @Override public void onSuccess(ResponseInfo<File> responseInfo) { manager.cancel(UPDATE_ID);//取消通知栏下载提示 //下载成功后自动安装apk并打开 File file = responseInfo.result; Intent intent = new Intent(Intent.ACTION_VIEW); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive"); context.startActivity(intent); } @Override public void onFailure(HttpException e, String s) { ToastUtil.show(context, "当前网络不可用,请检查网络设置"); } }); } else { ToastUtil.show(context, "当前网络不可用,请检查网络设置"); } } else { ToastUtil.show(context, "SD卡没有插好"); } } }
3.更新弹框布局文件dialog_update.xml:
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <RelativeLayout android:layout_width="310dp" android:layout_height="wrap_content" android:layout_centerInParent="true" android:background="@color/base_white" android:paddingBottom="20dp"> <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_marginBottom="20dp" android:layout_marginTop="20dp" android:text="发现新版本" android:textSize="20sp" /> <View android:id="@+id/line" android:layout_width="match_parent" android:layout_height="1dp" android:layout_below="@+id/title" android:background="#4a7acd" /> <TextView android:id="@+id/log_head" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/line" android:layout_marginLeft="20dp" android:layout_marginTop="20dp" /> <TextView android:id="@+id/msg_tv" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/log_head" android:layout_centerHorizontal="true" android:layout_marginLeft="32dp" android:layout_marginRight="32dp" android:text="更新日志" android:textSize="16sp" /> <LinearLayout android:layout_width="match_parent" android:layout_height="35dp" android:layout_below="@+id/msg_tv" android:layout_marginTop="30dp" android:orientation="horizontal"> <Button android:id="@+id/yes_btn" android:layout_width="0dp" android:layout_height="35dp" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" android:layout_weight="1" android:background="#4a7acd" android:gravity="center" android:text="立即更新" android:textColor="@color/base_white" android:textSize="16sp" /> <Button android:id="@+id/no_btn" android:layout_width="0dp" android:layout_height="35dp" android:layout_marginRight="20dp" android:layout_weight="1" android:background="#4a7acd" android:gravity="center" android:text="以后再说" android:textColor="@color/base_white" android:textSize="16sp" /> </LinearLayout> </RelativeLayout> </RelativeLayout>
