    	private static Stack<Activity> m_stack_activity;

    	private AppManager() {
    	}
    
    	/**
    	 * 单一实例
    	 */
    	public static AppManager getAppManager() {
    		if (m_instance == null) {

    	}

    			}
    		}
    	}
    
    	/**
    	 * 结束所有Activity
    	 */
    	public void finishAllActivity() {
    		for (int i = 0, size = m_stack_activity.size(); i < size; i++) {
    			if (null != m_stack_activity.get(i)) {
    				m_stack_activity.get(i).finish();
    			}
    		}
    		m_stack_activity.clear();
    	}
    
    	/**
    	 * 退出应用程序
    	 */
    	public void AppExit(Context context) {
    		try {			
    			finishAllActivity();
    			ActivityManager activityMgr = (ActivityManager) context
    					.getSystemService(Context.ACTIVITY_SERVICE);
    			activityMgr.restartPackage(context.getPackageName());
    			System.exit(0);
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
    	}
    }

使用

m_context = this;
    		// 添加Activity到堆栈
    		AppManager.getAppManager().addActivity(this);
    		// App String
    		AppString.init(m_context);
    		// 全局共享文件
    		String name = AppString.getAppName();
    		m_sharepref = new SharedPreferencesHelper(m_context, name);

/**
         * 跳转页面
         */
        public void enter() {
            Intent intent = new Intent(this, StartActivity.class);
            startActivity(intent);
            AppManager.getAppManager().finishActivity(this);
            overridePendingTransition(R.anim.push_left_in, R.anim.push_left_out);
        }

完！！！
