android 获取设备信息

///

Android 获取手机的厂商、型号、Android系统版本号、IMEI、当前系统语言等工具类

在开发中，需要用到一些系统信息的工具类有以下6个功能：

1、获取手机制造厂商

2、获取手机型号

3、获取手机系统当前使用的语言

4、获取Android系统版本号

5、获取手机IMEI串号

6、获取手机中的语言列表

SystemUtil类

/**
* 系统工具类
* Created by zhuwentao on 2016-07-18.
*/
public class SystemUtil {
/**
* 获取当前手机系统语言。
*
* @return 返回当前系统语言。例如：当前设置的是“中文-中国”，则返回“zh-CN”
*/
public static String getSystemLanguage() {
return Locale.getDefault().getLanguage();
}
/**
* 获取当前系统上的语言列表(Locale列表)
*
* @return 语言列表
*/
public static Locale[] getSystemLanguageList() {
return Locale.getAvailableLocales();
}
/**
* 获取当前手机系统版本号
*
* @return 系统版本号
*/
public static String getSystemVersion() {
return android.os.Build.VERSION.RELEASE;
}
/**
* 获取手机型号
*
* @return 手机型号
*/
public static String getSystemModel() {
return android.os.Build.MODEL;
}
/**
* 获取手机厂商
*
* @return 手机厂商
*/
public static String getDeviceBrand() {
return android.os.Build.BRAND;
}
/**
* 获取手机IMEI(需要“android.permission.READ_PHONE_STATE”权限)
*
* @return 手机IMEI
*/
public static String getIMEI(Context ctx) {
TelephonyManager tm = (TelephonyManager) ctx.getSystemService(Activity.TELEPHONY_SERVICE);
if (tm != null) {
return tm.getDeviceId();
}
return null;
}
}

其中获取手机IMEI需要在AndroidManifest.xml中加上权限：

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

使用这些方法的时候直接调用就好了

private void showSystemParameter() {
String TAG = "系统参数：";
Log.e(TAG, "手机厂商：" + SystemUtil.getDeviceBrand());
Log.e(TAG, "手机型号：" + SystemUtil.getSystemModel());
Log.e(TAG, "手机当前系统语言：" + SystemUtil.getSystemLanguage());
Log.e(TAG, "Android系统版本号：" + SystemUtil.getSystemVersion());
Log.e(TAG, "手机IMEI：" + SystemUtil.getIMEI(getApplicationContext()));
}

返回结果：

1.GPU 电压和频率


C:\Users\fadi.su>adb shell cat /proc/gpufreq/gpufreq_opp_dump
[0] freq = 450000, volt = 115000, idx = 0
[1] freq = 400000, volt = 111875, idx = 1

            String line;
            BufferedReader br = new BufferedReader(new FileReader("/proc/gpufreq/gpufreq_opp_dump"));
            while ((line = br.readLine()) != null) {
                result.add(line);
            }
            br.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
 
        return result;
    }

2.GPU 供应商和版本信息


        final RendererUtil mRendererUtil = new RendererUtil();
        GLSurfaceView mGLSurfaceView = (GLSurfaceView) mView.findViewById(R.id.surfaceView);
        mGLSurfaceView.setEGLContextClientVersion(1);

                mHandler.sendEmptyMessage(UPDATE_UI);
            }
        });

    }

4.运行结果

android获取GPU信息；android获取GPU渲染器、供应商、版本和扩展名等信息

效果：

1、布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="vertical"
android:layout_marginTop="15dp"
tools:context=".FirstActivity">

<android.opengl.GLSurfaceView
android:id="@+id/gl_surface_view"
android:layout_width="1dp"
android:layout_height="1dp"/>

</LinearLayout>

2、工具类

public static String glRenderer;
public static String glVendor;
public static String glVersion;
public static String glExtensions;

@Override
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
glRenderer = gl.glGetString(GL10.GL_RENDERER); //GPU 渲染器
glVendor = gl.glGetString(GL10.GL_VENDOR); //GPU 供应商
glVersion = gl.glGetString(GL10.GL_VERSION); //GPU 版本
glExtensions = gl.glGetString(GL10.GL_EXTENSIONS); //GPU 扩展名
}

@Override
public void onSurfaceChanged(GL10 gl, int width, int height) {

}

@Override
public void onDrawFrame(GL10 gl) {

}
}

3、活动

public class FirstActivity extends AppCompatActivity {
private TextView glRenderer;
private TextView glVendor;
private TextView glVersion;
private TextView glExtensions;
private GLSurfaceView glSurfaceView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.first_activity);
initView();
setData();
}

@Override
protected void onResume() {
super.onResume();
//延迟100毫秒再刷新一次，确保获取到GPU各项属性
handler.postDelayed(runnable,100);
}

//更新界面数据
private Handler handler = new Handler();
private Runnable runnable = new Runnable() {
public void run () {
setData();
}
};

private void setData(){
glRenderer.setText("GPU 渲染器: "+GpuInfoUtil.glRenderer);
glVendor.setText("GPU 供应商: "+GpuInfoUtil.glVendor);
glVersion.setText("GPU 版本: "+GpuInfoUtil.glVersion);
glExtensions.setText("GPU 扩展名: "+GpuInfoUtil.glExtensions);
}

private void initView(){
glRenderer = (TextView)findViewById(R.id.gpu_renderer);
glVendor = (TextView)findViewById(R.id.gpu_vendor);
glVersion = (TextView)findViewById(R.id.gpu_version);
glExtensions = (TextView)findViewById(R.id.gpu_extensions);

glSurfaceView= findViewById(R.id.gl_surface_view);
glSurfaceView.setEGLContextClientVersion(1);
glSurfaceView.setEGLConfigChooser(8, 8, 8, 8, 0, 0);
glSurfaceView.setRenderer(new GpuInfoUtil());
}
}

详解Android获得系统GPU参数 gl.glGetString

详解Android获得系统GPU参数 gl.glGetString

通过文档的查找，以及源码的剖析，Android的GPU信息需要通过OpenGL来获取，android framework层提供GL10来获取相应的参数，而GL10要在使用自定义的View时才可以获得，下面是获得GPU信息的例子：

1.实现Render类

class DemoRenderer implements GLSurfaceView.Renderer {

public void onSurfaceCreated(GL10 gl, EGLConfig config)
{
Log.d("SystemInfo", "GL_RENDERER = " +gl.glGetString(GL10.GL_RENDERER));
Log.d("SystemInfo", "GL_VENDOR = " + gl.glGetString(GL10.GL_VENDOR));
Log.d("SystemInfo", "GL_VERSION = " + gl.glGetString(GL10.GL_VERSION));
Log.i("SystemInfo", "GL_EXTENSIONS = " + gl.glGetString(GL10.GL_EXTENSIONS));
}

@Override
public void onDrawFrame(GL10 arg0) {
// TODO Auto-generated method stub

}

@Override
public void onSurfaceChanged(GL10 arg0, int arg1, int arg2) {
// TODO Auto-generated method stub

}

}

2.实现GLSurfaceView

class DemoGLSurfaceView extends GLSurfaceView {

DemoRenderer mRenderer;
public DemoGLSurfaceView(Context context) {
super(context);
setEGLConfigChooser(8, 8, 8, 8, 0, 0);
mRenderer = new DemoRenderer();
setRenderer(mRenderer);
}
}

3.在Activity中 new 一个 DemoGLSurfaceView 对象

4.设置这个View对象

public class Demo extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

GLSurfaceView glView = new DemoGLSurfaceView(this);

this.setContentView(glView);

}
