Question

我过去几天一直在学习领域，今天我决定测试我在Android上使用Realm开发的应用程序，以实现向后兼容。

模拟器详细信息：

Name: Nexus_4_API_10_2.3.3

CPU/ABI: ARM (armeabi)
Path: /home/mush/.android/avd/Nexus_4_API_10_2.3.3.avd
Target: default [Default] (API level 10)
Skin: nexus_4
SD Card: 100M
hw.dPad: no
runtime.network.speed: full
hw.accelerometer: yes
hw.device.name: Nexus 4
vm.heapSize: 64
skin.dynamic: yes
hw.device.manufacturer: Google
hw.gps: yes
hw.initialOrientation: Portrait
image.androidVersion.api: 10
hw.audioInput: yes
image.sysdir.1: platforms/android-10/images/
tag.id: default
showDeviceFrame: yes
hw.camera.back: emulated
hw.mainKeys: no

应用程序在启动引用LoginActivity.java作为错误源时立即崩溃。 Logcat代码段：

D/AndroidRuntime: Shutting down VM
W/dalvikvm: threadid=1: thread exiting with uncaught exception (group=0x40015560)
E/AndroidRuntime: FATAL EXCEPTION: main
                  java.lang.NoClassDefFoundError: _package_name_.sessions.LoginActivity
                      at _package_name_.SplashActivity.onCreate(SplashActivity.java:26)
                      at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047)

然后我继续注释掉调用LoginActivity.java的代码片段。

摘录：

//Check whether there's an active session first
        sessionManager = new SessionManager(getApplicationContext());
        if (sessionManager.isSessionActive()) {
            //Session is active => Launch the MainActivity
            Intent launchMainActivity = new Intent(getApplicationContext(), MainActivity.class);
            startActivity(launchMainActivity);
        } else {
            //Session is inactive => Launch the LoginActivity
            Intent launchLogin = new Intent(this, LoginActivity.class);
            startActivity(launchLogin);
            finish();
        }

这并没有解决我的问题。相反，Logcat会在此时停止，应用程序会在我的启动屏幕上冻结。

logcat的：

D/RealmManager: Initializing Realm configuration.
D/dalvikvm: DexOpt: couldn't find static field
W/dalvikvm: VFY: unable to resolve static field 118 (SUPPORTED_ABIS) in Landroid/os/Build;
D/dalvikvm: VFY: replacing opcode 0x62 at 0x0006
D/dalvikvm: VFY: dead code 0x0008-000c in Lcom/getkeepsafe/relinker/SystemLibraryLoader;.supportedAbis ()[Ljava/lang/String;
D/dalvikvm: Trying to load lib /data/data/_package_name_/lib/librealm-jni.so 0x40513a90`

该应用程序在Android API级别24上运行得非常好。这是否意味着领域向后兼容？

这是我的build.gradle文件：

apply plugin: 'com.android.application'
apply plugin: 'realm-android'
apply plugin: 'com.neenbedankt.android-apt'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.2"
    defaultConfig {
        applicationId "_package_name_"
        minSdkVersion 10
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        // Exclude file to avoid
        // Error: Duplicate files during packaging of APK
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
        exclude 'META-INF/services/javax.annotation.processing.Processor'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.0'
    compile 'com.android.support:design:24.2.0'
    compile 'com.android.support:recyclerview-v7:24.2.0'
    compile 'com.android.support:cardview-v7:24.2.0'
    compile 'com.jakewharton:butterknife:8.2.1'
    apt 'com.jakewharton:butterknife-compiler:8.2.1'
    compile 'dk.ilios:realmfieldnameshelper:1.0.0'
    compile 'io.realm:android-adapters:1.3.0'
    compile 'com.github.bumptech.glide:glide:3.7.0'
    compile 'com.squareup.okhttp3:okhttp:3.4.1'
    compile 'com.github.bumptech.glide:okhttp3-integration:1.4.0@aar'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha7'
}

我做错了什么？我该如何纠正呢。我会感激任何帮助。 PS：似乎没有其他类似StackOverflow的问题。这个one接近了。
