Solana transaction to start an account in the error of the Android application
As developers, we are committed to creating perfect and reliable applications that interact with the Blockchain ecosystem. In this case, our accounting program implemented in the Solana Devnet cluster depends on a specific transaction mechanism to start an account for users. However, our attempt to implement this transaction from an Android application has encountered problems.
The problem
Our accountable program uses anchor Lang, a rust -based structure for the construction of blockchain applications. We have created a simple interface that allows us to interact with the Cluster Solana Devnet through USA Anchor_lang :: Prelude ::*; macro. However, when trying to start an account using a transaction in the Android app, we find errors.
The solution
To solve this problem, we must create a separate service class that takes care of the transaction and initializes the Solana account. Here is an example of how we can do it:
`Rust
Use Anchor_lang :: Prelude ::*;
Declares_id! ("Init_account");
PUB FN INIT_ACCOUNT (
CTX: context
Keyyir: Keypair,
) -> result <(), string> {
// Create a transaction that starts the account creation process
Leave Mut Transaction = Iniccounttransation {
From: & keypair.public_key (),
A: & CTX.ACACOUNTS.Key_Pair.to Pubkey (),
Data: Some (& [[[
AccountMeta :: New (
"Account_name" .to_string (),
"Account_descript" .to_string (),
VEC! [],
) ,,
// ... Other metadata of the account ...
) ,,
};
// Send the transaction
Let results = anchor_lang :: transaction :: new (
&transaction,
& [],
& [& CTX.ACCOUNTS.Key_pair],
)?;
// Check that the transaction has been successful successful
Result of correspondence {
Ok (_) => {
Println! ("Successfully initialized account.");
Ok (())
}
Er (er) => {
Eprintln! ("Error that starts the account: {}", er);
Err.to_sting ())
}
}
Ok (())
}
Mod init_account {
Use Super ::*;
Pub Stuct avtaccountransation {
// ...
}
Anchorscript impl for initacounttransation {
Fn Init (
_Ctx: & Mut context
Keyyir: Keypair,
) -> result
// ...
}
}
}
In this example, we define a separate gradeInit_Cacount ‘service that deals with the transaction and initializes the Solana account. We have created an application for “initacounttransation”, which contains the metadata necessary for the process of creating the account. The `Init ‘method is where we send the transaction to the network.
Conclusion
By creating a separate service class that deals with the transaction and start of the Solana account, we have solved the problem of our Android app which does not start an account in the Cluster Devnet. This approach allows us to dissociate our logic of application from Blockchain transactions and guarantees reliability and scalability in our overall solution.
