我似乎无法在较旧的Android手机上运行android studio项目

标签： java android android-studio android-api-levels

我正在为我的一个大学编码类（用Java编写）开发一个游戏项目，并且正在使用Android Studio。尽管我是Android Studio的新手，但我了解Java基础知识。我的主要问题与在较旧的API / SDK版本上（尤其是在较旧的手机上）运行/测试项目有关。

尽管我还安装了Pie（API 28），但我一直在基于API 26的Android 8.0（Oreo）上进行开发。当前，我的targetSDKVersion是26，compileSDKVersion是26，而我的minSDKVersion是19。

我正在尝试在Samsung Galaxy S4（API 19）上运行我的应用程序（称为AMaze），这就是为什么我的minSDKVersion为19的原因。据我所知，它在支持Android 8.0及更高版本的手机上运行完全正常知道。但是，当我在Galaxy S4上运行该应用程序时，它打开并崩溃，并立即显示“很遗憾，您的应用程序已停止”。我不知道该怎么解决。

我已经在StackOverflow和Android Developers网站上搜索了答案，但是运气很小。我尝试使用gradle清理和重建项目，尝试禁用Instant Run，并尝试使compileSDKVersion 19而不是26（但这会使编译器感到恼火，说Google Play要求它26岁或以上）。我假设我的手机与Android兼容（请参阅https://developer.android.com/guide/practices/compatibility），并且我按照说明将手机连接到计算机（https://developer.android.com/training/basics/firstapp/running-app）。根据开发者网站，它要做的所有事情就是将minSDKVersion设置为正确的级别，并针对代码中的所有API弃用和更新进行调整（我认为我已经做到了）。但这仍然行不通。

我发现的是我的代码在我的主要活动（称为AMazeActivity）的onCreate（）方法中产生了膨胀异常。似乎各种原因都可能导致此错误，但我无法找出根本原因。这个家伙有类似的情况： android.view.InflateException: Binary XML file: Error inflating class fragment

这是在手机上运行应用程序后收到的全部错误消息。错误消息说我的充气异常是由于试图给Spinner充气：

这是我的主要活动中发生崩溃的地方。我尝试将代码放在try / catch块中，以捕获异常并将其更干净地打印出来，如上所示：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        try {

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_amaze);
        }
        catch (Exception e) {
            e.getCause();
            Log.e("AMazeActivity", "onCreate", e);
            throw e;
        }
.  .  .
.  .  .

注意事项：我在活动中使用约束布局，在程序中仅使用一个自定义视图，并且未使用自定义主题。这是异常抱怨Spinner的XML文件：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    tools:context="cs.cs301.amaze.gui.AMazeActivity">

   .  .  .

    <TextView
        android:id="@+id/diff_JFrame"
        android:layout_width="248dp"
        android:layout_height="60dp"
        android:layout_marginStart="16dp"
        android:layout_marginTop="256dp"
        android:text="Difficulty/Size"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

   .  .  .

    <Spinner
        android:id="@+id/mazeGen"
        android:layout_width="248dp"
        android:layout_height="35dp"
        android:layout_marginStart="16dp"
        android:layout_marginEnd="120dp"
        android:layout_marginBottom="130dp"
        android:entries="@color/colorAccent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        />
   .  .  .

我认为可能只是更改设置中的几行（也许在gradle，清单文件，R类，XML文件等中），但是我不知道要更改什么或在哪里更改。任何帮助将不胜感激！

答案 0 :(得分：0)

更改此行

android:entries="@color/colorAccent"

到

android:entries="@array/yourarrayname"
