at com.example.amgad.medikar.MainActivity.onCreate(MainActivity.java:71)

该行

 scanner = new ImageScanner();

所以我试图手动加载库

 static{
    System.loadLibrary("libiconv");
    System.loadLibrary("libzbarjni");
}

然后我收到了这个错误

Answer 1

使用：

static {
    System.loadLibrary( "iconv" );
}

有关更多信息，请查看ZBarAndroidSDK-0.2中的包样本。

Answer 2

就我而言，我的项目中也有其他.so库。

我做的是：

将每个.so文件放在正确的cpu类型下（正如您已经做过的）
将所有cpu文件夹放在名为＆＃34; lib＆＃34;的另一个文件夹中。
zip lib文件夹并将其重命名为lib.jar
将lib.jar放在app libs文件夹
按照上面的建议添加System.loadLibrary( "iconv" );

将此行添加到构建

dependencies {
 compile fileTree(dir: 'libs', include: '*.jar') }

希望这有帮助

android studio 785中的zbar无法加载所需的库＆＃39; libiconv.so＆＃39;为＆＃39; libzbarjni.so＆＃39;
