工具類如下:

public class NetEnvironmenApi {

    private static final int COUNT = 8;//連續點選一個按鈕次數，切換為測試環境

    private static final int TIP_COUNT = 4;

    private long lastClickTime = 0;//上一次點選的時間

    private int clickCount = 0;//點選的次數

    private SoftReference<Context> context;

    private static final NetEnvironmenApi ourInstance = new NetEnvironmenApi();

    public static NetEnvironmenApi getInstance() {
        return ourInstance;

    public boolean checkAdd() {
        long time = System.currentTimeMillis();
        if (time - lastClickTime > 1000) {//兩次間隔時間過長，重新計算
            lastClickTime = time;
            clickCount = 1;
        } else {
            clickCount++;
            lastClickTime = time;
        }
        if (clickCount >= COUNT) {
            return true;
        } else {
            return false;
        }
    }

    public int getLeftCount() {

    }

    /**

     */
    public boolean isShowTips() {
        return clickCount >= TIP_COUNT;
    }

    /**
     * 建立標記為測試環境的檔案
     */
    public boolean createDebugFile() {
        try {
            if (context == null || context.get() == null) {
                return false;
            }
            File file = new File(context.get().getCacheDir(), FILE_NAME);
            if (!file.exists()) {
                return file.createNewFile();
            } else {
                return true;
            }
        } catch (IOException e) {
        }
        return false;
    }

    private String FILE_NAME = "debug";

    /**
     * 是否為測試環境
     *
     * @return
     */
    public boolean isDebugEnv() {
        if (context == null || context.get() == null) {
            return false;
        }
        File file = new File(context.get().getCacheDir(), FILE_NAME);
        if (file.exists()) {
            return true;
        } else {
            return false;
        }
    }

    /**
     * 切換為正式環境
     *
     * @return
     */
    public boolean changeToRelease() {
        if (context == null || context.get() == null) {
            return false;
        }
        File file = new File(context.get().getCacheDir(), FILE_NAME);
        if (file.exists()) {
            return file.delete();
        }
        return true;
    }

}

 

然後點選多次進入測試環境:

if (NetEnvironmenApi.getInstance().checkAdd()) {
                    boolean isCreate = NetEnvironmenApi.getInstance().createDebugFile();
                    if (isCreate) {
                        Toast.makeText(MainActivity.this, "切換為測試環境", Toast.LENGTH_LONG).show();
                        new Handler().postDelayed(new Runnable() {
                            @Override
                            public void run() {
                                Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage(getApplication().getPackageName());
                                LaunchIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                                startActivity(LaunchIntent);
                                android.os.Process.killProcess(android.os.Process.myPid());
                            }
                        }, 500);
                    } else {
                        Toast.makeText(MainActivity.this, "切換為測試環境失敗", Toast.LENGTH_LONG).show();
                    }
                } else {
                    if (NetEnvironmenApi.getInstance().isShowTips()) {
                        Toast.makeText(MainActivity.this, "再點選" + NetEnvironmenApi.getInstance().getLeftCount() + "次進入測試環境", Toast.LENGTH_LONG).show();
                    }
                }
 

點選按鈕，切換為正式環境:

if (NetEnvironmenApi.getInstance().changeToRelease()) {
                    Toast.makeText(MainActivity.this, "切換為正式環境", Toast.LENGTH_LONG).show();
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage(getApplication().getPackageName());
                            LaunchIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                            startActivity(LaunchIntent);
                            android.os.Process.killProcess(android.os.Process.myPid());
                        }
                    }, 500);

                }
 

其實就是在手機的SD卡中增加一個檔案來判斷。
