<p>Starting with the 1.5 release of go-ethereum, we've transitioned away from shipping only full blown Ethereum clients and started focusing on releasing the code as reusable packages initially for Go projects, then later for Java based Android projects too.

<p>Under the hood the Android library is backed by a go-ethereum light node, meaning that given a not-too-old Android device, you should be able to join the network without significant issues.

*This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed behind a proxy. Since a proxied contract can't have a constructor, it's common to move constructor logic to an external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer function so it can only be called once. The {initializer} modifier provided by this contract will have this effect. TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}. CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.*

This is not verified automatically as constructors are by Solidity. [CAUTION] ==== Avoid leaving a contract uninitialized. An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation contract, which may impact the proxy. To initialize the implementation contract, you can either invoke the initializer manually, or you can include a constructor to automatically mark it as initialized when it is deployed: [.hljs-theme-light.nopadding] ```*
