android获取手机信息

1.获取手机安装的应用信息（排除系统自带）：

 

 

private String getAllApp() {
        String result = "";
        List<PackageInfo> packages = getPackageManager().getInstalledPackages(0);
        for (PackageInfo i : packages) {
            if ((i.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0) {
                result += i.applicationInfo.loadLabel(getPackageManager()).toString() + ",";
            }
        }
        return result.substring(0, result.length() - 1);
}

 以字符串的形式返回应用的名字app1,app2,app3,...........apps    中间的以","分开。当然还可以得到包名，icon图标，等等 。

 

2.获取手机可用内存和总内存：

 

 

 private String[] getTotalMemory() {
        String[] result = {"",""};  //1-total 2-avail
        ActivityManager.MemoryInfo mi = new ActivityManager.MemoryInfo();  
        mActivityManager.getMemoryInfo(mi);  
        long mTotalMem = 0;
        long mAvailMem = mi.availMem;
        String str1 = "/proc/meminfo";
        String str2;
        String[] arrayOfString;
        try {
            FileReader localFileReader = new FileReader(str1);
            BufferedReader localBufferedReader = new BufferedReader(localFileReader, 8192);
            str2 = localBufferedReader.readLine();
            arrayOfString = str2.split("\\s+");
            mTotalMem = Integer.valueOf(arrayOfString[1]).intValue() * 1024;
            localBufferedReader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        result[0] = Formatter.formatFileSize(this, mTotalMem);
        result[1] = Formatter.formatFileSize(this, mAvailMem);
        Log.i(TAG, "meminfo total:" + result[0] + " used:" + result[1]);
        return result;
    }

 手机的内存信息主要在/proc/meminfo文件中，其中第一行就是总内存，而剩余内存可通过 ActivityManager.MemoryInfo得到 。

 

3.手机CPU信息

 

 

private String[] getCpuInfo() {
        String str1 = "/proc/cpuinfo";
        String str2 = "";
        String[] cpuInfo = {"", ""};  //1-cpu型号  //2-cpu频率
        String[] arrayOfString;
        try {
            FileReader fr = new FileReader(str1);
            BufferedReader localBufferedReader = new BufferedReader(fr, 8192);
            str2 = localBufferedReader.readLine();
            arrayOfString = str2.split("\\s+");
            for (int i = 2; i < arrayOfString.length; i++) {
                cpuInfo[0] = cpuInfo[0] + arrayOfString[i] + " ";
            }
            str2 = localBufferedReader.readLine();
            arrayOfString = str2.split("\\s+");
            cpuInfo[1] += arrayOfString[2];
            localBufferedReader.close();
        } catch (IOException e) {
        }
        Log.i(TAG, "cpuinfo:" + cpuInfo[0] + " " + cpuInfo[1]);
        return cpuInfo;
    }

 和内存信息同理，cpu信息可通过读取/proc/cpuinfo文件来得到，其中第一行为cpu型号，第二行为cpu频率。

 

4.获取手机MAC地址：

 

 

private String getMacAddress(){
        String result = "";
        WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        WifiInfo wifiInfo = wifiManager.getConnectionInfo();
        result = wifiInfo.getMacAddress();
        Log.i(TAG, "macAdd:" + result);
        return result;
    }

 MAC地址比较容易，直接通过WifiManager得到。

 

4.IMEI号，IESI号，手机型号等：

 

 

private void getInfo() {
        TelephonyManager mTm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
        String imei = mTm.getDeviceId();
        String imsi = mTm.getSubscriberId();
        String mtype = android.os.Build.MODEL; // 手机型号
        String numer = mTm.getLine1Number(); // 手机号码，有的可得，有的不可得
    }

 

5.获取手机屏幕高度：

 

 

 private void getWeithAndHeight(){
        //这种方式在service中无法使用，
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        String width = dm.widthPixels;              //宽
        String height = dm.heightPixels;           //高

        //在service中也能得到高和宽
        WindowManager mWindowManager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
        width = mWindowManager.getDefaultDisplay().getWidth();
        height = mWindowManager.getDefaultDisplay().getHeight();
    }

 

 

未完。。。
