ExceptionInInitializerError、java.security.NoSuchAlgorithmException: no such algorithm: ECDSA for pro

在集成Tron-java Sdk后运行发现总是异常

java.security.NoSuchAlgorithmException: no such algorithm: ECDSA for provider BC

解决办法：

1.在application的onCreate里面加入下面的方法

public void setupBouncyCastle() {
        final Provider provider = Security.getProvider(BouncyCastleProvider.PROVIDER_NAME);
        if (provider == null) {
            // Web3j will set up the provider lazily when it's first used.
            return;
        }
        if (provider.getClass().equals(BouncyCastleProvider.class)) {
            // BC with same package name, shouldn't happen in real life.
            return;
        }
        // Android registers its own BC provider. As it might be outdated and might not include
        // all needed ciphers, we substitute it with a known BC bundled in the app.
        // Android's BC has its package rewritten to "com.android.org.bouncycastle" and because
        // of that it's possible to have another BC implementation loaded in VM.
        Security.removeProvider(BouncyCastleProvider.PROVIDER_NAME);
        Security.insertProviderAt(new BouncyCastleProvider(), 1);
    }

2.在AndroidMainfest.xml中添加代码：

此时运行就正常了。
