在 "Application type" 選項中怠晴，選擇 "Android"：
- 輸入 Name。
- 在 Signing-certificate fingerprint 中輸入您的應用程序簽名證書的 SHA-1 指紋浴捆。如果您不知道如何獲取 SHA-1 指紋蒜田，請參考這篇文章。
- 在 Package name 中輸入您的 Android 應用程序的包名选泻。包名必須與您實際應用的包名一致冲粤，否則授權(quán)將無法成功。
點擊 Create∫趁校現(xiàn)在梯捕，您將看到您的 Client ID。請務必安全地保存這些信息窝撵，稍后將在您的應用程序中使用它們傀顾。
Android端依賴
implementation 'com.google.android.gms:play-services-auth:19.2.0'

implementation 'com.google.api-client:google-api-client-android:1.23.0'
Android端代碼
1.初始化服務，
private lateinit var googleSignInClient: GoogleSignInClient
private var isRecover: Boolean=false
private val RC_SIGN_IN = 9001
private fun initDrive() {
val signInOptions = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.requestScopes(Scope(DriveScopes.DRIVE_FILE))
.build()
googleSignInClient = GoogleSignIn.getClient(this, signInOptions)
}
切記 使用 requestScopes(Scope(DriveScopes.DRIVE_FILE)) 而不是 .requestIdToken(ApiAction.SERVER_CLIENT_ID)
.requestIdToken(ApiAction.SERVER_CLIENT_ID)是登錄注冊使用的
2.具體業(yè)務邏輯
點擊事件
views.backupGoogle.debouncedClicks {
if (isGooglePlayServicesAvailable(this)) {
isRecover = false
getDriveAuth()
} else {
T.showShort(this, "設備不支持谷歌登錄")
}
}
views.recoverGoogle.debouncedClicks {
if (isGooglePlayServicesAvailable(this)) {
isRecover = true
getDriveAuth()
} else {
T.showShort(this, "設備不支持谷歌登錄")
}
}
詳細方法
fun isGooglePlayServicesAvailable(context: Context): Boolean {
val googleApiAvailability = GoogleApiAvailability.getInstance()
val resultCode = googleApiAvailability.isGooglePlayServicesAvailable(context)
return resultCode == ConnectionResult.SUCCESS
}
private fun getDriveAuth() {
val signInIntent = googleSignInClient.signInIntent
startActivityForResult(signInIntent, RC_SIGN_IN)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == RC_SIGN_IN) {
val task = GoogleSignIn.getSignedInAccountFromIntent(data)
handleSignInResult(task)
}
}
private fun handleSignInResult(completedTask: Task<GoogleSignInAccount>) {
try {
val account = completedTask.getResult(ApiException::class.java)
account?.let {
// Get a Drive service instance using the signed-in account.
getDriveService(this, it)?.let {drive->
lifecycleScope.launch(Dispatchers.IO) {
if(isRecover){
BackupUtil.restoreData(drive, "backup.txt").let { content->
L.v("===content==${content}")
}
}else{
BackupUtil.backupData(drive, privateHex, "backup.txt")
}
}
}
}
} catch (e: ApiException) {
L.v("=====signInResult:failed code=" + e.statusCode)
}
}
BackupUtil代碼碌奉，里面有覆蓋上傳以及更新上傳短曾，自我斟酌
