我正在尝试创建一个测试示例,其中我将TextView的内容设置为存储在IPFS中的文件的内容.
我正在使用此存储库来执行我的功能:https://github.com/ipfs/java-ipfs-api
我一直在多个地方看到似乎是多索引错误despit启用multidex:
defaultConfig {
applicationId "*****"
minSdkVersion 26
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
**multiDexEnabled true**
}
dependancies{
implementation 'com.android.support:multidex:1.0.0'
}
MainActivity.java:
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
这是我得到的错误:

这是我的代码:
TextView example = view.findViewById(R.id.example);
IPFS ipfs = new IPFS("/ip4/127.0.0.1/tcp/4001");
try {
ipfs.refs.local();
NamedStreamable.ByteArrayWrapper file = new NamedStreamable.ByteArrayWrapper("hello.txt", "G'day world! IPFS rocks!".getBytes());
MerkleNode addResult = ipfs.add(file).get(0);
Multihash filePointer = Multihash.fromBase58("QmPZ9gcCEpqKTo6aq61g2nXGUhM4iCL3ewB6LDXZCtioEB");
byte[] fileContents = ipfs.cat(filePointer);
this.example.setText(new String(fileContents));
} catch (IOException e) {
e.printStackTrace();
}
编辑: 我在安装jitpack和java-ipfs-api之前没有收到此错误
laz*_*bug 18
刚遇到同样的问题，这是因为某些库使用Java 8功能，在您的情况下应该是java-ipfs-api。要解决此问题，请在build.gradle文件中添加以下代码，以将Android Gradle插件配置为支持Java 8，并确保使用最新的Android gradle插件：
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
从这里采取的解决方案。
你的代码并不重要。错误是“无法打开 dex 文件 [...] 错误的方法句柄类型 7 ”。
\n\nMethodHandleType 定义于art/libdexfile/dex/dex_file.h
enum class MethodHandleType : uint16_t { // private\n kStaticPut = 0x0000, // a setter for a given static field.\n kStaticGet = 0x0001, // a getter for a given static field.\n kInstancePut = 0x0002, // a setter for a given instance field.\n kInstanceGet = 0x0003, // a getter for a given instance field.\n kInvokeStatic = 0x0004, // an invoker for a given static method.\n kInvokeInstance = 0x0005, // invoke_instance : an invoker for a given instance method. This\n // can be any non-static method on any class (or interface) except\n // for \xe2\x80\x9c<init>\xe2\x80\x9d.\n kInvokeConstructor = 0x0006, // an invoker for a given constructor.\n kInvokeDirect = 0x0007, // an invoker for a direct (special) method.\n kInvokeInterface = 0x0008, // an invoker for an interface method.\n kLast = kInvokeInterface\n };\n因此，在您的情况下，您可以看到您的方法之一是直接（特殊）方法的调用程序（我猜它指的是DMH）。它被添加到提交631827d中。
\n\n此时，我想知道您是否遇到了围绕 java 8 支持的艺术错误；因为在 dex 中成功脱糖的东西不会在本领域中执行失败。
