Methods whose names start with`detect`specify what problems we should look for. Methods whose names start with`penalty`specify what we should do when we detect a problem. You can call as many`detect`and`penalty`methods as you like. Currently order is insignificant: all penalties apply to all detected problems. For example, detect everything and log anything that's found: ```kotlin StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() .detectAll() .penaltyLog() .build(); StrictMode.setThreadPolicy(policy); ``` ## Summary | Public constructors ||

Public constructors ### Builder Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` Builder() ``` Creates a Builder that detects nothing and has no violations. (but note that[build](https://developer.android.com/reference/kotlin/android/os/StrictMode.ThreadPolicy.Builder#build())will default to enabling[penaltyLog](https://developer.android.com/reference/kotlin/android/os/StrictMode.ThreadPolicy.Builder#penaltyLog())if no other penalties are specified) ### Builder Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` Builder(policy: StrictMode.ThreadPolicy!) ``` Initializes a Builder from an existing ThreadPolicy. ## Public methods ### build Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun build(): StrictMode.ThreadPolicy! ``` Constructs the ThreadPolicy instance. Note: if no penalties are enabled before calling`build`,[penaltyLog](https://developer.android.com/reference/kotlin/android/os/StrictMode.ThreadPolicy.Builder#penaltyLog())is implicitly set. ### detectAll Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun detectAll(): StrictMode.ThreadPolicy.Builder ``` Detects everything that's potentially suspect.

This helps detect accidental type mismatches and potentially expensive type conversions when obtaining typed resources. For example, a strict mode violation would be thrown when calling[android.content.res.TypedArray#getInt(int, int)](https://developer.android.com/reference/kotlin/android/content/res/TypedArray.html#getInt(kotlin.Int,%20kotlin.Int))on an index that contains a String-type resource. If the string value can be parsed as an integer, this method call will return a value without crashing; however, the developer should format the resource as an integer to avoid unnecessary type conversion. | Return || |-------------------------------------------------------------------------------------------------------------------------------|-----------------------------| | [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/kotlin/android/os/StrictMode.ThreadPolicy.Builder#) | This value cannot be`null`. | ### detectUnbufferedIo Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun detectUnbufferedIo(): StrictMode.ThreadPolicy.Builder ``` Detects unbuffered input/output operations. | Return || |-------------------------------------------------------------------------------------------------------------------------------|-----------------------------| | [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/kotlin/android/os/StrictMode.ThreadPolicy.Builder#) | This value cannot be`null`. | ### penaltyDeath Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun penaltyDeath(): StrictMode.ThreadPolicy.Builder ``` Crashes the whole process on violation. This penalty runs at the end of all enabled penalties so you'll still get see logging or other violations before the process dies. Unlike[penaltyDeathOnNetwork](https://developer.android.com/reference/kotlin/android/os/StrictMode.ThreadPolicy.Builder#penaltyDeathOnNetwork()), this applies to disk reads, disk writes, and network usage if their corresponding detect flags are set. | Return || |-------------------------------------------------------------------------------------------------------------------------------|-----------------------------| | [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/kotlin/android/os/StrictMode.ThreadPolicy.Builder#) | This value cannot be`null`. | ### penaltyDeathOnNetwork Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun penaltyDeathOnNetwork(): StrictMode.ThreadPolicy.Builder ``` Crashes the whole process on any network usage. Unlike[penaltyDeath](https://developer.android.com/reference/kotlin/android/os/StrictMode.ThreadPolicy.Builder#penaltyDeath()), this penalty runs*before* anything else. You must still have called[detectNetwork](https://developer.android.com/reference/kotlin/android/os/StrictMode.ThreadPolicy.Builder#detectNetwork())to enable this.
