我将所有相应库的compileSDK API版本从22更改为25。现在我签名的应用程序崩溃了。
这是我的stacktrace:

这是我的build.gradle文件:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.package.Main"
versionCode 46
versionName '1.1.7'
minSdkVersion 14
targetSdkVersion 25
project.ext.set("archivesBaseName", "app-" + defaultConfig.versionName);
multiDexEnabled true
}
buildTypes {
release {
println "Running proguard"
minifyEnabled true
shrinkResources true
proguardFiles 'proguard-project.txt'
}
debug {
minifyEnabled false
}
}
lintOptions {
abortOnError false
}
productFlavors {
}
useLibrary 'org.apache.http.legacy'
}
dependencies {
compile 'com.android.support:support-v4:25.2.0'
compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.google.android.gms:play-services-ads:8.4.0'
}
这是按钮,应用程序崩溃了:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/bg_color"
android:gravity="center_horizontal"
xmlns:ads="http://schemas.android.com/apk/res-auto">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
android:id="@+id/buttonConnect"
android:layout_width="match_parent"
android:layout_height="@dimen/action_measure_height"
style="@style/YellowButton"
android:layout_marginBottom="@dimen/action_margin_horizontal"
android:layout_marginTop="@dimen/action_margin_horizontal"
android:text="@string/button_connect"/>
<com.google.android.gms.ads.AdView
android:id="@+id/adView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
ads:adSize="SMART_BANNER"
ads:adUnitId="@string/admob_publisher_id"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_alignWithParentIfMissing="true"
android:gravity="center" />
</RelativeLayout>
</LinearLayout>
这是gradle设置:
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
}
我尝试了在本网站上找到的所有建议,但没人工作。 看起来,它会在资源中找到的每个按钮上崩溃。 任何想法,如何解决这个问题?
