android手機管家鎖住其它APP,發現有點流氓,后臺一個線程在不停的運行 大致的核心代碼如下:起時在service中啟動這個類,但做測試為圖個方便直接在Activity中啟動 package com.example.testsafe;import android.content.Context; import android.content.pm.ApplicationInfo; import android.content.pm.PackageInfo; import android.content.pm.PackageManager; import android.content.pm.PackageManager.NameNotFoundException;public class ApkInfo extends ApplicationInfo{private String appname;private String pname;private String versionName;private int versionCode;private PackageInfo packageInfo;public static ApkInfo getInfoFromPackageName(String pkgName,Context mContext) {ApkInfo newInfo = new ApkInfo();try {PackageInfo p = mContext.getPackageManager().getPackageInfo(pkgName, PackageManager.GET_PERMISSIONS);newInfo.appname = p.applicationInfo.loadLabel(mContext.getPackageManager()).toString();newInfo.pname = p.packageName;newInfo.versionName = p.versionName;newInfo.versionCode = p.versionCode;newInfo.setPackageInfo(p);} catch (NameNotFoundException e) {e.printStackTrace();return null;}return newInfo;}public String getAppname() {return appname;}public void setAppname(String appname) {this.appname = appname;}public String getPname() {return pname;}public void setPname(String pname) {this.pname = pname;}public String getVersionName() {return versionName;}public void setVersionName(String versionName) {this.versionName = versionName;}public int getVersionCode() {return versionCode;}public void setVersionCode(int versionCode) {this.versionCode = versionCode;}public PackageInfo getPackageInfo() {return packageInfo;}public void setPackageInfo(PackageInfo packageInfo) {this.packageInfo = packageInfo;}}
