Android获取一些常用信息

获取版本号和版本名：

PackageManager pm = context.getPackageManager();
PackageInfo pi = pm.getPackageInfo(context.getPackageName(), 0);
versionName = pi.versionName;
versioncode = pi.versionCode;

手机型号、系统版本号、sdk版本号

手机型号：android.os.Build.MODEL

sdk版本号：

android.os.Build.VERSION.SDK_INT

[/code]

android系统版本号：android.os.Build.VERSION.RELEASE

获取手机分辨率；宽、高

WindowManager windowManager = getWindowManager();
Display display = windowManager.getDefaultDisplay();
int screenWidth = screenWidth = display.getWidth();
int screenHeight = screenHeight = display.getHeight();

IMEI：仅仅对android手机有效，需要添加权限

<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

TelephonyManager TelephonyMgr = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
String szImei = TelephonyMgr.getDeviceId();

打电话：

权限<uses-permission android:name="android.permission.CALL_PHONE">
</uses-permission>

Intent phoneIntent = new Intent("android.intent.action.CALL",
Uri.parse("tel:"+ inputStr));
