Question

我开发了一个应用，这个应用有两个版本。在旧版本上安装新版本应用程序时。它显示应用程序未安装。

我的 list :

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/smsbox_2_logo"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:screenOrientation="portrait"
        android:theme="@style/AppTheme">
        <activity
            android:name=".activities.Main_Page"
            android:label="@string/app_name"
            android:screenOrientation="portrait"></activity>
        <activity
            android:name=".activities.addSMS_Page"
            android:label="@string/title_activity_new_sms"
            android:screenOrientation="portrait" />
        <activity
            android:name=".activities.ShowSMS_Page"
            android:label="@string/title_activity_show_sms__page"
            android:screenOrientation="portrait" />
        <activity
            android:name=".activities.MySMS_Page"
            android:label="@string/title_activity_my_sms__page"
            android:screenOrientation="portrait" />
        <activity
            android:name=".activities.Fav_Page"
            android:label="@string/title_activity_fav__page"
            android:screenOrientation="portrait" />
        <activity
            android:name=".activities.login_Page"
            android:label="@string/title_activity_login__page"
            android:screenOrientation="portrait"></activity>
        <activity
            android:name=".activities.register_Page"
            android:label="@string/title_activity_register__page"></activity>
        <activity
            android:name=".activities.category_Page"
            android:label="@string/title_activity_register__page"></activity>
        <activity
            android:name=".activities.category_select_Page"
            android:label="@string/title_activity_register__page"></activity>
        <activity
            android:name=".activities.about_Page"
            android:label="@string/title_activity_about__page"></activity>
        <activity
            android:name=".activities.setting_Page"
            android:label="@string/title_activity_setting__page"></activity>
        <activity
            android:name="com.tellfa.smsbox.activities.splash_Page"
            android:label="@string/title_activity_splash__page">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".activities.connectus_Page"
            android:label="@string/title_activity_connectus__page"></activity>
    </application>

</manifest>

Build.Gradle 代码:

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.tellfa.smsbox"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 10
        versionName "2.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),         'proguard-rules.pro'
        }
    }
}

如何解决？
