Android获取手机的版本号等信息的代码

本文实例分享了android获取手机系统版本等信息的方法，供大家参考，具体内容如下：

第一种代码：

string phoneinfo = "product: " + android.os.build.product;
phoneinfo += ", cpu_abi: " + android.os.build.cpu_abi;
phoneinfo += ", tags: " + android.os.build.tags;
phoneinfo += ", version_codes.base: " + android.os.build.version_codes.base;
phoneinfo += ", model: " + android.os.build.model;
phoneinfo += ", sdk: " + android.os.build.version.sdk;
phoneinfo += ", version.release: " + android.os.build.version.release;
phoneinfo += ", device: " + android.os.build.device;
phoneinfo += ", display: " + android.os.build.display;
phoneinfo += ", brand: " + android.os.build.brand;
phoneinfo += ", board: " + android.os.build.board;
phoneinfo += ", fingerprint: " + android.os.build.fingerprint;
phoneinfo += ", id: " + android.os.build.id;
phoneinfo += ", manufacturer: " + android.os.build.manufacturer;
phoneinfo += ", user: " + android.os.build.user;
textview t = (textview) findviewbyid(r.id.main_phoneinfo);
t.settext(phoneinfo);

第二种代码：

private string gethandsetinfo(){ 
string handsetinfo= 
“手机型号:” + android.os.build.model + 
“,sdk版本:” + android.os.build.version.sdk + 
“,系统版本:” + android.os.build.version.release+ 
“,软件版本:”+getappversionname(mainactivity.this); 
return handsetinfo;

} 
//获取当前版本号 
private string getappversionname(context context) { 
string versionname = “”; 
try { 
packagemanager packagemanager = context.getpackagemanager(); 
packageinfo packageinfo = packagemanager.getpackageinfo(“cn.testgethandsetinfo”, 0); 
versionname = packageinfo.versionname; 
if (textutils.isempty(versionname)) { 
return “”; 
} 
} catch (exception e) { 
e.printstacktrace(); 
} 
return versionname; 
} 

第三种代码：获得手机型号,系统版本,app版本号等信息，具体代码：

mainactivity如下:

package cn.testgethandsetinfo; 
import android.os.bundle; 
import android.text.textutils; 
import android.widget.textview; 
import android.app.activity; 
import android.content.context; 
import android.content.pm.packageinfo; 
import android.content.pm.packagemanager; 
/** 
* demo描述: 
* 获得手机型号,系统版本,app版本号等信息 
*/ 
public class mainactivity extends activity { 
private textview mtextview; 
@override 
protected void oncreate(bundle savedinstancestate) { 
super.oncreate(savedinstancestate); 
setcontentview(r.layout.main); 
init(); 
} 
private void init(){ 
mtextview=(textview) findviewbyid(r.id.textview); 
mtextview.settext(gethandsetinfo()); 
} 
private string gethandsetinfo(){ 
string handsetinfo= 
"手机型号:" + android.os.build.model + 
",sdk版本:" + android.os.build.version.sdk + 
",系统版本:" + android.os.build.version.release+ 
",软件版本:"+getappversionname(mainactivity.this); 
return handsetinfo; 
} 
//获取当前版本号 
private string getappversionname(context context) { 
string versionname = ""; 
try { 
packagemanager packagemanager = context.getpackagemanager(); 
packageinfo packageinfo = packagemanager.getpackageinfo("cn.testgethandsetinfo", 0); 
versionname = packageinfo.versionname; 
if (textutils.isempty(versionname)) { 
return ""; 
} 
} catch (exception e) { 
e.printstacktrace(); 
} 
return versionname; 
} 
} 

main.xml如下:

<relativelayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
> 
<textview 
android:id="@+id/textview" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:text="@string/hello_world" 
android:layout_centerinparent="true" 
/> 
</relativelayout> 

最后一段代码：

phoneinfo = "product: " + android.os.build.product; 
    phoneinfo += ", cpu_abi: " + android.os.build.cpu_abi; 
    phoneinfo += ", tags: " + android.os.build.tags; 
    phoneinfo += ", version_codes.base: " + android.os.build.version_codes.base; 
    phoneinfo += ", model: " + android.os.build.model; 
    phoneinfo += ", sdk: " + android.os.build.version.sdk; 
    phoneinfo += ", version.release: " + android.os.build.version.release; 
    phoneinfo += ", device: " + android.os.build.device; 
    phoneinfo += ", display: " + android.os.build.display; 
    phoneinfo += ", brand: " + android.os.build.brand; 
    phoneinfo += ", board: " + android.os.build.board; 
    phoneinfo += ", fingerprint: " + android.os.build.fingerprint; 
    phoneinfo += ", id: " + android.os.build.id; 
    phoneinfo += ", manufacturer: " + android.os.build.manufacturer; 
    phoneinfo += ", user: " + android.os.build.user;
