相关疑难解决方法(0)

我正在尝试导入我的项目.但是当我运行应用程序时,我收到以下错误:

Error: Execution failed for task ':app:processDebugResources'.
 > com.android.ide.common.process.ProcessException:      
   org.gradle.process.internal.ExecException: Process 'command 'C:\Users\Vishnu  Ruhela\AppData\Local\Android\sdk\build-tools\21.1.2\aapt.exe'' finished with non- zero exit value 1

这是我的gradle文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"
    defaultConfig {
        applicationId "com.example.vishnuruhela.signup"
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors { }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile project(':listView1')
}

我正在使用Android studio 3.0
我已经厌倦了解决这个问题.应用程序不执行它总是显示此错误二进制XML文件行#0:错误膨胀类ImageView

这是我的main_activity.xml,我已经改变了我使用ConstraintLayout的xml

  <?xml version="1.0" encoding="utf-8"?>

主要活动的java代码

public class MainActivity extends Activity {
Button btn1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_activity);//the error point here
    btn1 = (Button) …

我的应用程序的某些用户遇到此崩溃,似乎可能与三星设备有关.有没有其他人遇到过这个问题并找到了解决方案？
