Question

我使用最低要求的Android Marshmallow使用Android Studio制作了一个应用...

应用程序可以在My Motorola Moto G6和OnePlus 6上完美运行！

但是它已安装但仍在Samsung J7 nxt，Redmi Note 4，Redmi Note 5上崩溃... 所有手机均为Android Oreo / Pie

有解决方案吗？

尝试重新安装并清除重新启动缓存的n个内容。

编辑：

我现在知道原因了！！这是我的LoadingActivity.java

我在不加载活动的情况下编译了.apk [加载活动只是在应用程序启动时带有app_Logo的屏幕]。

这是我的代码，请让我知道怎么了。

完美适用于： 1.摩托罗拉Moto G6-Android 9 2.三星J7 NXT-Android 9 3. Oneplus 6-Android 9

加载活动于：崩溃 1. Samsung Galaxy Grand Max-Android 4.4.4 [确定太旧了] 2. Redmi Note 5-Android 8 3. Redmi注意事项4

代码： LoadingActivity.java（java类）

XML activity_loading：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="#000000">

    <ImageView
        android:layout_width="225sp"
        android:layout_height="225sp"
        android:src="@drawable/app_logo"
        android:layout_gravity="center"
        android:layout_marginTop="75sp"
        android:layout_centerHorizontal="true"
        android:contentDescription="App Logo"/>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="APPNAME"
        android:gravity="center_horizontal"
        android:fontFamily="@font/arial"
        android:textColor="#CFCFCF"
        android:textSize="30sp"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="60sp"/>



</RelativeLayout>

我在切换活动时使用IF-ELSE是有原因的。我希望少数品牌的手机可以参加其他活动，以后再编码。目前，所有电话都重定向到“登录”。

原因已知应用已停止工作！！仅适用于少数几个，但不适用于其他
