結(jié)合這段時(shí)間的技術(shù)調(diào)研，做個(gè)總結(jié)：
1.針對(duì)5.0以上的安卓系統(tǒng)虎谢，有系統(tǒng)API:可以使用android.app.usage.UsageStatsManager,閑話(huà)不多說(shuō)盟榴，直接po代碼如下：
? ?mUsageStatsManager= (UsageStatsManager).getSystemService(Context.USAGE_STATS_SERVICE);
? ?Calendar cal = Calendar.getInstance();
? ?cal.add(Calendar.YEAR, -1);
? List queryUsageStats = getUsageStatistics(1);
? PackageManager pm = getApplicationContext().getPackageManager();
for(inti =0; i < queryUsageStats.size(); i++) {
? ? ? ? ? ? UsageStats usageStats = queryUsageStats.get(i);
? ? ? ? ? ? ?Class c = usageStats.getClass();
try{
//mLaunchCount 我理解的它就是是app啟動(dòng)次數(shù)，這是被@hide修飾的成員變量嘉冒。只能用反射得到它的值曹货。但是有個(gè)現(xiàn)象是，啟動(dòng)次不
//準(zhǔn)讳推，從桌面點(diǎn)進(jìn)去記數(shù)2顶籽，從后臺(tái)進(jìn)入記數(shù)1，時(shí)間間隔為一天银觅，總的統(tǒng)計(jì)次數(shù)也不準(zhǔn)確
? ? ? ? ? ? ? Field field = c.getDeclaredField("mLaunchCount");
? ? ? ? ? ? ? ?field.setAccessible(true);
? ? ? ? ? ? ? ?Field field1 = c.getDeclaredField("mBeginTimeStamp");
? ? ? ? ? ? ? ?field1.setAccessible(true);
? ? ? ? ? ? ? ?Field field2 = c.getDeclaredField("mEndTimeStamp");
? ? ? ? ? ? ? ?field2.setAccessible(true);
? ? ? ? ? ? ? ? ApplicationInfo applicationInfo = pm.getApplicationInfo(usageStats.getPackageName(), ? ? ? ? ? ? ? ? ?PackageManager.GET_META_DATA);
? ? ? ? ? ? ? ?String appName = pm.getApplicationLabel(applicationInfo).toString();
? ? ? ? ? ? ? ?PackageInfo packageInfo = pm.getPackageInfo(usageStats.getPackageName(),0);
//應(yīng)用首次裝時(shí)間
? ? ? ? ? ? ? ? longfirstInstallTime = packageInfo.firstInstallTime;
//格式化成年月日
? ? ? ? ? ? ? ? String firstInstallTime1 = transferLongToDate("yyyy-MM-dd HH:mm:ss", firstInstallTime);
//應(yīng)用最后一次更新時(shí)間
? ? ? ? ? ? ? ?long lastUpdateTime = packageInfo.lastUpdateTime;
? ? ? ? ? ? ? ?String lastUpdateTime1 = transferLongToDate("yyyy-MM-dd HH:mm:ss", lastUpdateTime);
? ? ? ? ? ? ? ? Log.i("應(yīng)用:"+usageStats.getPackageName(),"first install time : "+ firstInstallTime1 +" last update time :"+ lastUpdateTime1);
//這部分的時(shí)間礼饱，我沒(méi)有搞太明白，請(qǐng)自行驗(yàn)證
long firstTimeStamp = usageStats.getFirstTimeStamp();

long mBeginTimeStamp = field1.getLong(usageStats);
String mBeginTimeStamp1 = transferLongToDate("yyyy-MM-dd HH:mm:ss", mBeginTimeStamp);
long mEndTimeStamp = field2.getLong(usageStats);
String mEndTimeStamp1 = transferLongToDate("yyyy-MM-dd HH:mm:ss", mEndTimeStamp);
//這部分的時(shí)間究驴，我沒(méi)有搞太明白镊绪，請(qǐng)自行驗(yàn)證
? ? ? ? ? ? ? ? Log.i("使用列表...field...","應(yīng)用名："+ appName +"\n包名："+ usageStats.getPackageName() +"\nfirstTimeStamp:"+ ? ? ? ? ? ? ? firstTimeStamp1

}catch(Exception e) {
? ? ? ? ? ? ? ?e.printStackTrace();

關(guān)于5.0以上系統(tǒng)統(tǒng)計(jì)啟動(dòng)次數(shù)，系統(tǒng)提供API不準(zhǔn)熙侍，如果不在第三方應(yīng)用植入自己的sdk,統(tǒng)計(jì)第三方應(yīng)用的啟動(dòng)次數(shù)不靠譜榄鉴，但是要收集安裝時(shí)間是可以的。
